USBHCD is an updated USB host controller drivers: USBUHCD.SYS,USBOHCD.SYS,USBEHCD.SYS,USBD.SYS and USBRESMG.SYS
 
 
Version History
10.197: USBEHCD.SYS:
- fix trap in isochronous processing (cancel iso processing). Necessary for USBAUDIO.SYS and USBECD.SYS in isochronous mode
- read all 32-bit timestamps atomically. Necessary in order to prevent incorrect time diff computation for delay loops
- do not attempt to clear a stalled default (endpoint zero) pipe
 
USBUHCD.SYS:
- read all 32-bit timestamps atomically. Necessary in order to prevent incorrect time diff computation for delay loops
- fix in isochronous processing in order to prevent possible memory overflow
- do not attempt to clear a stalled default (endpoint zero) pipe
      
USBD.SYS:
- various small fixes in order to properly handle stall of status change pipe (has an influence on device insertion)      
- on client driver registration, do not call driver for all known devices (will happen later on device insertion anyway)
       
USBOHCD.SYS:
- read all 32-bit timestamps atomically. Necessary in order to prevent incorrect time diff computation for delay loops
- do not attempt to clear a stalled default (endpoint zero) pipe
 
USBRESMG.SYS:
- unchanged
