However, when we plugged it in, it enumerated with the same driver as the TRENDnet TU-S9, and operated perfectly with the downloaded Prolific driver. The Sabrent SBT-USC1M worked flawlessly for us, but only after updating with a new driver v2.0.13.130 downloaded in file PL2303_Prolific_DriverInstaller_v110.zip (12/2/2009) from [.]. -- the driver from the included mini-CD-ROM wasn't tested by us, because the disc had a fracture crack and couldn't be read by our CD reader. Our torture testing included self-loopback on an XP laptop, from COM1 (internal UART serial port) to COM14 (where our TRENDnet port showed up), sending a thousdand 1099-byte blocks at 115200bps from one program to another, which echoed the blocks back to the first program for comparison after short delay. [So, this is really "half-duplex" testing, but that's what we bought them for, so that's what we tested].
I bought this adapter as a test unit, and I've put it through its paces. It's entirely possible this is a Windows quirk, and not the device/driver's fault. I didn't get a chance to test the driver disc.
Modern Linux kernels detect the device with no user interaction. The device works well in all three operating systems. I've tried it in Windows, Linux, and OS X.
The packaging doesn't include instructions for downloading drivers online, but a quick Google search found the download site. OS X and Windows require a driver install. The adapter ships with a mini cd with Windows drivers.
I rated four stars in compatibility because I had the device map to a different COM port in Windows a couple times, which made creating a saved connection a bit of a hassle. Overall, I'm quite pleased.
I never got to use this cable. The plastic housing surrounding the serial connection was too deep to allow the pins to make contact with my machine. This wasn't obvious to me from the illustration. I ended up tossing it in the junk drawer.
This cable was exactly what I needed, or so I thought. I couldn't get the my laptop to recognize my serial devices with this cable.
I was a little skeptical about some feedback concerning it's operation, but after getting it I plugged it up to my Garmin GPS, went online, and downloaded updates with no problem. For me, the price and product can't be beat. Shipping didn't really take that long either.
