Got a new (cheap) USB to RS-232 adapter - CD that came with it was blank.
Only info in device properties is:
usb\\vid_0000&pid_0000\\5&42A229B&0&1

Can anybody help me?

Well I thought I would just write off my big expense, but this is what I have.

Think both that I bought have PL-2303 chips.
Where I bought them -
http://www.amazon.com/gp/offer-listing/B002WPR8JC/ref=dp_olp_new?ie=UTF8&qid=1315939342&sr=1-21&condition=new 59c Importer520

And bought for 30c this http://www.amazon.com/gp/offer-listing/B000S5FAF2/ref=sr_1_15_olp?s=electronics&ie=UTF8&qid=1316802391&sr=1-15&condition=new
...... Both had CDs , one was blank. Downloaded from net a new driver, still get
"cannot start (code 10) on one and "unknown device" on other. Win XP and Win 7 on two machines.

Looks like the URLs didn't survive Tom's filters, but if you google B000K02UP8 , it should come up with a picture ad of the device with a (Prolific PL2303HX Chipset)

My computers are HP laptop and homemade, both running XP Pro ver 5.1 SP3

Also tried the adapters in a machine running Win 7 ver 7000? beta - same end result.
