I have repeated failure to install hardware via USB. Failed installs include a Cannon printer, Minolta camera and a card reader. Some time ago, installation of Epsom printer and HP scanner worked ok. Installation wizard cannot find driver on supplied CD's or says it is not "digitally signed and may not work properly". In the case of the printer I appeared to get the driver installed (eventually) but printer would not work (it works OK on son's W98 machine). Camera and Card reader have been complete installation failures. WXP was supplied pre-installed on PC with recovery disc. Vendor not very helpful.
