Sub=00 Prot=00 Driver=pl2303 The ones that I have at hand all look like this: T: Bus=05 Lev=01 Prnt=01 Port=01 Cnt=02 Dev#= 3 Spd=12 MxCh= 0 D: Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 P: Vendor=067b ProdID=2303 Rev=03.00 S: Manufacturer=Prolific Technology Inc.

Sub=00 Prot=00 Driver=pl2303 So, yours and mine are all type 'HX' according to the driver's categorization ... The only common differences would be the product description string having a "D" suffix in your version and bmAttributes being 0xa0 vs. 0x80, so yours claim to support remote wakeup. The former seems like a bad idea to base hardware detection on, but the latter might indicate a different chip with different features?! Can you tell what the physical chip is labeled as, if anything? @Johan: What does the USB device info of your adapter(s) say? Regards, Florian
