        Does anyone have Bulk In working with Windows 8? I have an application that has worked for years on XP and 7 but simply will not work with Windows 8. Ive tried with the same hardware on both win 7 and 8 - with CyUSB and with CyUSB3 - the win8 installation always fails Bulk In request with 997. Im suspecting a URB issue, but just want to know if Im chasing the impossible or not?

 Which USB controleer are you using?

   

 

   

use USBlyzer http://www.usblyzer.com/ to check the USB trace.

   

 

   

if you are getting 997 means probably there is no data in the BULK endpoint .

        part number: CY7C68013A100AXC-TQFP100 I have used Microsoft Message Analyzer - that shows the Bulk In Request was Cancelled. IT says "URB information missing". Helpfully it doesn't say what is missing though. I will try with the analyser you suggested. The board works perfectly well with windows xp & windows 7.
