Got me further than any others, though I was still prompted (annoyingly) to manually browse my way to find the SER2PL.SYS file (repeatedly), which luckily DOES reside on the mini-CD that came with the cable. GOOD NEWS (sort of): Running the driver (its an EXE) Dave listed at: No luck, and Windows XP Pro continued marking this device as 'Unable to Start' with a yellow exclamation point in Device Manager. Tried all the HL-340 drivers, all the PL-2302, and finally the CH-341 (Chinese) drivers Dave pointed to. *IMPORTANT NOTE: At first, I think my PC simply didn't appreciate the cable being plugged into its front USB ports, and further progress was made by plugging it into one of the 8 rear ports!*

Many thanks to Dave for trying his best to wrangle all the drivers needed for 'generic' USB-to-RS232 cables like mine, but no luck for me after many attempts. I'm a computer tech with 27 years experience, so this should've been a no brainer.

but other reviewers suggested HL-340 (not contained on the CD!). And it's unclear what exact model the cable is. Unfortunately, all the drivers are contained on a mini-CD and not well organized. I wanted so much to feel the love, and get this darn (cheap) USB-to-serial cable working, but no luck for the longest time.īought item #8757 (funny, that's also part of the device's PID it seems) from DealExtreme, waited weeks for delivery, and hoped I'd have luck with the included drivers.
