Hello
Could yout point me a reason why grabbing datas from usb device these datas
includes some incorrect numbers ? Is it synchronization or what ??
I put it in my endpoint2 fifo buffer incrementing datas ( from 1 to 64).
I wrote a device driver and I use it to read these datas from.
I insert fr
No, it is not safe to DMA from the stack in all architectures.

Is it OK to have the USB transfer buffer (parameter 7 to usb_control_msg())
in kernel stack?
The documentation says that "This buffer has to be allocated as a
non-pageable contiguous physical memory block" and if it's placed in stack
it works on x86, but is it safe thing to do across all architect

Hi !
I am testing PPP over the Bluetooth stack using Usb as a transport
medium in VXWORKS.
I am using Ericsson ROC101008 Bluetooth module with an usb
support in it. And OHCI controller as a Host.
Initially i receives ping response from the peer, quite well..
As time goe
