Hi David,

  Attached below is the error msg i got when trying to enumerate the DLINK WUSB HUB

It seems that the DN_CONNECT go thru juzt fine, but when sending urb packet to enumerate the hub (i think ??), there is error in the function __wa_xfer_is_done, case WA_SEG_ABORTED, which cause the abort to occur.BTW, when sending data frame over WUSB to the HUB, just curious if the  endpoint address to be 01 for OUT, instead of 0 (default control endpoint) , as i printed out the value of endpoint address to be 0. thx again for your info !

The WUSB hub (DWA) won't do anything useful because there's no DWA
driver.  However, you should be able to authenticate and enumerate it.

Could you expand on the error messages?  It may be useful to build the
driver with additional debugging.
