Other Parts Discussed in Thread: TUSB8041
Evaluation board for TUSB8041: Ports 1&2 failed for "device descriptor request failed" and Ports 3&4 functional. Note that SW1 and SW2 all are set to default (as shipped) which is OFF positions. Same USB sticks functions at ports 3 &4 and multiple computers w/o the TUS8041EVM boards.
Have gone thru the steps of unistalling devices 1&2, checking for new drivers, chkdsk/reboot/cclean etc/, turn on fast startup, changing USB selective suspend setting, Will all these steps , problem still persists for downstream ports 1 &2.
