Dear Wolfgang Denk,
The commit 5dd95cf93dfffa1d19a1928990852aac9f55b9d9 'usb_storage: Fix EHCI "out of buffer pointers" with CD-ROM' introduce a bug in usb_storage as it wrongly assumes that every transfer can use 4096 bytes per qt_buffer. This is wrong if the start address of the data is not page aligned to 4096 bytes and leads to 'EHCI timed out on TD' messages because of 'out of buffer pointers' in ehci_td_buffer function.
The bug appears during load of a fragmented file and read from or write to an unaligned memory address.
