Hello. Is it possible to allocate large buffers for bulk transfer with vmalloc_32 function? I need buffer about 4 Mb. I allocated it with vmalloc_32 function. After that usb_submit_urb() returned success but instead data which i wanted to receive in buffer was nothing. I've read the mailing list archive and i've seen that that question was discussed and people have the same problems but i didn't find the answer that vmalloc_32 must not use for memory allocation.
