linux-usb-users,您好!

              hi,everybody~~

                  i would like to ask a usb bus reset issue when i working on 
isp1582 usb2.0 peripheral device controller.

                  that's > I read the usb2.0 spec ,and found that the usb bus 
reset should force to the device when device first 

                  attached or the device receiveSE0 or idle after Timer0 times 
out.

                  but I got usb reset many times ,rightly after usb enmuation 
finished or disk device can be found on PC ,and beginning 

                  to carry out the scsi command.

                  I have no idea why usb reset so much??  the enmuation can 
finished successfully when i force the isp1582 in full-speed.
  
          and sometimes failed if set in high-speed mode.

          can anyone give me some tips?? or light me something??

              best regards:)  

        致
礼!
