## Description

Review: Works Well - But incompatible with Windows11 - Great device, worked first time no issues. Until I upgraded to Windows 11, this chipset is not compatible with Windows 11.
Review: Working with Linux, Virtualbox and Windows XP/7 - It is functioning nicely as a means of controlling my NIR spectrometer via the spectrometer's parallel D25 serial connection, using a D25 to D9 serial adapter. My PC lacks the now scarce D9 serial port, so a USB to Serial D9 cable represents my only option. This Ugreen cable has a chip inside, in order for it to be recognised by Ubuntu 20.04 linux OS, which it is, natively. The NIR spectrometer software requires Windows XP or Windows 7 but a Virtualbox virtual machine (VM) runs both Windows OS's as guest OS's under Ubuntu 20.04 LTS host OS. This cable enables a serial connection on Virtualbox as serial host machine (not host pipe). Select the dummy guest Windows COM port, IRQ and address and save. Be sure to allow all users read access to the USB serial host device in a linux terminal, using: " sudo chmod 666 /dev/ttyUSB0". After setting up the VMs and configuring the serial connection it worked very well. I would have opted for a longer cable than the one metre length, had this been an option, but a Ugreen USB male to female extension cable privided the necessary reach from PC on my desk to table with NIR spectrometer. Overall a very useful cable indeed.

## Questions & Answers

**Q: does this work with a microsoft surface?**
A: Hi Mr.M, it would work well Win10/8.1/8 with PL2302 chipset, if your system is windows RT, you need to chose this cable with FTDI chipset.ASIN B00QUZY4L0.

**Q: will this work with windows 10**
A: Yes. I have just tried by installing the Windows 8 drivers from the included mini-disc of drivers, and connecting it to my elderly Garmin E-Trex H. I was using the GPS to enter my site coordinates into a planetarium software programme and it worked just fine. This was using a laptop previously running 8.1 and recently upgraded to Windows 10. To my inexperienced eye it appears to be a well made cable which I bought specifically for W 8.1 but am delighted to discover that it also works with W10. Hope this helps.

**Q: Hi, does this work with cisco products?**
A: it dosent work with all cisco. routers ok switches not so much. better off getting startec one with ftdi chipset, that one definatly works. had to junk this one

**Q: Does it work on linux?**
A: Yes, It work well with Linux.Carol

### ⭐⭐⭐⭐⭐ Good cable that works
*by M***D on 22 July 2025*

Used this to debug a device that only supported serial connections, you may need to install a usb driver to convert the serial to usb for mac or windows but the cable works.
