USBEHCD.SYS: changes in resetting the HC on system boot / HC reset b.) IMPORTANT: changes to USBD.SYS. version 10.162 has a fundamental design flaw that prevents it from handling devices that return configuration data > 1024 bytes. In practice, many USB 2.0 web cams have > 1024 bytes of configuration data. As a first step, I had to change the USBD interface towards client drivers (something like usbprt.sys, usbmouse.sys, usbser.sys etc.) . There might be client drivers around that act as filter drivers and these can be affected. It is possible that these will subsequently trap this updated USBD.SYS. If this happens, I would be interested to know. I still haven't updated USBD.SYS to support > 1024 bytes of config data (this will be the next step) but I have added some code to prevent the traps that used to happen with USBD.SYS 10.162 when you'd attach such web cam device with > 1024 bytes of config data. In any case, USBD.SYS is still experimental. Important note: make sure that USBEHCD.SYS goes after USBUHCD.SYS/USBOHCD.SYS in config.sys ! I have not yet succeeded in coming up with a solution that would render config.sys sequence irrelevant.
