First I got myself one of those USB to RS232 adapters. Didn't work. Today I received my ExpressCard RS232 adapter. The god damn driver doesn't work -- Windows keeps saying "The system cannot find the file specified." and that's all. It shows up in Device Manager as "USB-Serial Controller D"... which is awfully strange given that it's an ExpressCard and so should have nothing at all to do with USB (I think?). Device Manager gives the following "Device Id": USB\VID_067B&PID_2303\5&37F53AEF&0&2 It seems to think it's a Prolific USB to RS232 adapter. Anyone got any idea how I can get this working in Windows XP SP3? -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
