[U-Boot-Users] isp116x-hcd and usb_storage

[tike64]

Dear List,

I'm trying to set usb host up on our board (LH7A400 + ISP1160). It
already works to some extend; it detects my Kingston 1GB stick. But
then it (usb reset) fails with "Request Sense returned 00 00 00". Funny
thing is that it starts to work if I enable debugging messages in
usb_storage.c and isp116x-hcd.c. If I enable them in usb_storage.c
only, it doesn't work. Here is the debug message log with debugging
enabled in usb_storage.c only till the first difference I can see:

================================

ptr[4] is different when I have debugging enabled in both files:

================================

ptr[8] 0x0 ptr[9] 0x0 ptr[10] 0x0 ptr[11] 0x0
ptr[12] 0x0
inquiry returns 0

================================

Could someone please help in debugging this?
