I plugged in a Wyse keyboard and mouse and it all works fine . I then plugged in a generic USB keyboard when the S90 was booted into XPe and it was detected OK but when I restarted the S90 without the Wyse Keyboard the generic keyboard it did not work at all .and the S90 would not even boot into XPE …Its as if it must have a Wyse keyboard plugged in for it to boot to XPE
Surely you do not need a Wyse Keyboard and mouse to get the S90 with Xpe to load up ????
