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:
================================

================================
Could someone please help in debugging this?
