StarTech.com USB to Serial Hub — 8-Port COM Port Retention, Rack Mount, and Daisy Chainable FTDI USB to RS232 Hub

The StarTech.com USB to Serial Hub is a factory‑level solution engineered to bring robust RS232 serial connectivity to modern industrial environments. Designed around a durable, enterprise‑grade enclosure and a high‑reliability FTDI chipset, this 8‑port USB to RS232 hub lets you quickly expand your serial port footprint without sacrificing performance or stability. It’s ideal for manufacturing floors, data acquisition systems, POS deployments, lab automation, and other scenarios where dozens of serial devices must share a single host or be deployed across a rack. With COM port retention, rack‑mount compatibility, and daisy‑chain capabilities, this hub provides a scalable, cost‑effective path to reliable serial communications in both new installations and legacy setups. Marine‑grade builds aren’t required when you’re in a harsh industrial plant, but the rugged construction and thoughtful design stand up to everyday wear and tear while delivering consistent, predictable performance.

  • Effortless expansion of serial ports: Add 8 RS232 ports to a single USB host to connect multiple devices such as barcode scanners, PLCs, CNC machines, robots, sensors, and test rigs. The hub consolidates devices that would otherwise require numerous USB adapters, simplifying cabling and management while preserving a clean rack or desk space.
  • COM port retention for simplified software deployment: The hub preserves COM port numbering across reconnects and reboots, reducing the likelihood of software reconfiguration when devices are swapped or rebooted. This feature is especially valuable for legacy software that relies on fixed COM port assignments, saving time during installation and maintenance.
  • Rack‑mountable, daisy‑chain capable design: Built to integrate into 19" racks with included mounting hardware, the hub minimizes footprint in control rooms and data centers. For larger deployments, you can daisy‑chain multiple hubs to scale port counts without sacrificing performance, making it easy to accommodate growing serial device networks.

how to install StarTech.com USB to Serial Hub

1) Prepare your environment and hardware: Unbox the hub and verify you have the included 19" rack‑mount brackets if you plan to install it in a rack. Ensure you have a spare USB 2.0 port on your host computer or USB hub and access to the RS232 devices you intend to connect.

2) Connect the hub to the host: Use the included USB cable to connect the hub’s USB port to a free USB 2.0 port on your computer or USB hub. If you intend to run a large number of devices or anticipate high power demands, consider connecting to a powered USB hub or providing external power to the hub as recommended by your system requirements.

3) Install drivers and verify driver status: On Windows, the operating system may automatically install the FTDI drivers. On macOS and Linux, you may need to install FTDI drivers or use the built‑in FTDI support provided by your distribution. Confirm the drivers are loaded correctly by checking the device manager (Windows) or running system diagnostics to confirm the FTDI device is present.

4) Connect serial devices to the hub: Attach your RS232 devices to the eight available DB9 ports. Ensure each device is properly powered and configured for the expected baud rates and settings. The COM port numbers will be assigned by the OS according to the FTDI mapping and will be retained if COM Port Retention is active.

5) Configure software and test communication: Open your serial software and select the corresponding COM ports assigned to each device. Validate data exchange, error rates, and timing for all devices. If you encounter discrepancies, verify cable integrity, baud rate compatibility, and proper termination for distant devices. If you plan to expand later, you can safely add additional hubs in a daisy‑chain configuration and map the new ports in your software.

6) Mounting and final checks: If you’re deploying in a rack, secure the hub with the supplied brackets and confirm cable management keeps power and data lines orderly. Perform a final power‑on cycle and run a quick test suite to ensure all eight ports operate as expected in routine workflows.

I feel fully enveloped in the work
Size: 34"/WQHD/1000R/HDR400
Changed my work at home experience. I feel fully enveloped in the work. I don't use it for gaming so can't comment on that. But for laptop heavy work days, this is a great experience.

Simple and not Drama claim process.
’ve had Asurion coverage for a couple of years and never needed to use it until recently, when my pool salt cell (less than two years old) stopped working. I had purchased it with an Asurion protection plan, so I contacted them to start a claim. The process was simple and straightforward to follow. In the end, they honored the plan and covered the cost of my salt cell based on the value when I originally bought it. They issued me a gift card that I could use on Amazon for that amount. While prices have gone up and a new cell now costs about $200 more, it was still definitely worth having the coverage. Overall, I’m satisfied with how the claim was handled.

Love this protection plan
Quick and easy. My daughter's cracked her screen on her phone, as soon as it happened I went on the app, filed the claim. Ten minutes later I received the email with the shipping lable. The following day I dropped the phone off at ups and 4 hours later I received the digital gift card. Ive filed several claims since getting the protection plan and with four kids its definitelysomething im glad to have especially since i dont have to buy a protectionplan for each item now. I have filed claims for electric scooter the stoped working for no reason, my son's phone stopped charging, my oldest daughter cracked her phone screen, my son's video game controllers up and died and each time it was quick and easy and no fuss

Don't waste your money - these people will not help you
On March 9th 2024, I purchased a MCombo Lift Chair costing $785. On the same day, through the same Amazon account (my PERSONAL account since I also have a business account), I purchased an Asurion Complete Protect policy at the cost of $16.99 per month plus taxes. About one month ago, a problem arose with the chair that required me to make a claim using the "Complete Protect" policy that I had purchased for that very item. The claim was initiated on January 1st, 2025 - On January 3rd, I received an email asking me for photographs showing the damage for which I was making a claim. I sent those photographs via email to the address provided on January 6th. On January 27th, having not received ANY response from Asurion, I contacted them via phone and was told that my purchase had been made with a business account, that it was being used for business purposes, and was therefore not covered. I assured the Asurion Representative that it was most certainly not a business use, and that the chair that I was claiming for had been purchased because I had extensive shoulder surgery done that made it impossible to get in and out of bed. After speaking (unsuccessfully) with the Asurion Rep, I then contacted Amazon Customer Service. I spoke with an Amazon Customer Service Representative on the phone who confirmed that I had in fact used my personal account to purchase the chair and the Asurion Complete Protect policy. That representative went on to send a message to Asurion on my behalf confirming that the purchase was for personal use and not business use. Asurion responded, asking me to call them with the order number for the Asurion purchase. The number I gave was the exact same order number on my order history, however, the Asurion Rep could not find it. I was finally able to discover that the order number in Asurion's system was entirely different and isn't even in the same format as an Amazon order number. Upon the Asurion representative finding my plan, she informed me that the chair was listed as being purchased for business use (despite Amazon confirming that it was NOT) but that I should give them "a couple of business days" to resolve the issue. Five business days later, still no response and so I called them again (Yesterday - February 1st 2025)... Lo and behold, I got the same crap yet again... the purchase was listed as business use and was therefore being denied, but she promised to remove the business use commentary and put the claim through again. Today, February 2nd, I called Amazon yet again to escalate and had to call THREE times because the first two calls resulted in me finally being connected to an Asurion representative (two different reps) and each time, the Asurion representative hung up the phone as soon as my name was mentioned. It has become clear to me that the Asurion "Complete Protect" policy is a SCAM - they will NOT take care of your issue, regardless of how long you've been paying. I have been paying every month since March 9th last year - so they've received over $170 from me thus far, with zero other claims, and if I am able to cancel right now, I will only receive $16.99 back. All I want, is the chair that I purchased the policy for coverage of, to be repaired or replaced. Asurion are NOT helping, and are actively avoiding contact. At this point, I am considering legal action against Asurion for fraud - perhaps even a Class Action. I'll wait and see if my issue gets resolved within the next 10 days or so.

Asurion is AWESOME!
Ok, so let me start with the fact that you should NOT waste your time calling Amazon's customer service if you think you have a claim under Asurion's monthly protection plan. CALL ASURION! I wasted almost an hour with Amazon representatives that have absolutely no training in how the Asurion plan works, or even any idea if my item was covered. In fact, they told me the mechanized chair I purchased under the plan wasn't covered! Finally, my call got escalated to a manager who was just as clueless about my coverage, but had the best idea ever... call Asurion! The smartest thing I did that morning was hang up with Amazon, and reach out to Asurion as I should have done in the first place. Dealing with Asurion's customer service, after my Amazon call, was like being elevated to VIP status! 😄 Asurion's rep nicely took all my info, including the chair's purchase date and order number. Then they asked that I upload a couple of pictures of the product, along with a written description of the malfunction I had mentioned over the phone. This is where it gets really good. They told me they'd review the claim to determine if they'd send a repair specialist or reimburse me the cost of the item. In less than 48 hours, they determined that a payout was in order, and sent me an email that included an Amazon gift card for the total cost of the item minus the taxes I had paid, which I loaded directly into my Amazon wallet. Apparently, Asurion does not include the purchase taxes in their coverage. But, I can live with that. All in all, Asurion's claims division get a double thumbs up 👍🏽👍🏽, and the company gets big ups from me for not only standing behind their protection plan, but doing so expeditiously! Special note: If you buy a lot of stuff from Amazon, and have Asurion's monthly protection plan, scroll the item listing before pulling the trigger on your purchase... you need to see the green streamer that indicates your product is protected by the plan. If you don't see that, check to see if there are alternative products that might be covered. There are very few electronic or high ticket items that aren't covered, but looking for that green banner in the item description that says it's covered is key to foregoing any future headaches.
