Backed by a StarTech..

Review: Works perfectly - We use this with multiple laptops that download from GPS units and need to be reliable and simple. Telling people how to use Device Manager to find where the USB-Serial adapter went doesn't cut it. I can now configure the machines once and know it'll work every time. It installed perfectly on Windows XP, Windows 7 32-bit and Windows 7 64-bit. The fact that it arrives packed in an anti-static bag inside a cardboard box makes it clear it's not the typical cheap blister pack unit.
Review: Get the right one! - Be sure to check your COMPUTER and the signature pad you are ordering to make sure it's the correct one. Once we got the correct signature pad, this works perfectly. Easy to hook up...just find a USB port on your computer!

## Questions & Answers

**Q: The instruction booklet says windows XP - - Is there a newer version available ?? (provide link)**
A: It worked with my Windows 10

**Q: Will this work on a MacBook with the M1 Chip?**
A: Hello! I work as an IT Admin for 5 dealerships in the Midwest region. My experience with this adapter is that it did not work for my intentions. We hook MDI Vehicle Diagnostic equipment to a computer using this adapter, and it did not function with the provided drivers. The same drivers are available for Mac OS X, so they should work on an A1 Mac, assuming you need this for a supported function. I believe our issue was a software limitation on GM's side. I'm unsure what you're needing this for, but the one that worked for us can be found here: https://www.amazon.com/Tripp-Lite-Serial-Adapter-U209-000-R/dp/B00005V52C/ref=asc_df_B00005V52C/?tag=hyprod-20&linkCode=df0&hvadid=309773039951&hvpos=&hvnetw=g&hvrand=1341244576104308830&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9023343&hvtargid=pla-432061054982&psc=1

**Q: Is this compatible with windows 10?**
A: Yes, ICUSB232PRO is compatible with Windows 10.

Sam, StarTech.com Support

**Q: The instruction booklet says it is only compatible with windows 98/me/2000/xp  - these have been anchient for 20 years  - - safe for win 10/11 ?**
A: Startech is slow to update stuff. I have both this unit and the unit that is USB-C, and have used both on Windows 10. The USB-C seems to connect quicker, but both work.
