Subject: usbhid: How to wait for response after submitting report
Date: Sat, 13 Mar 2010 13:10:39 +1000 [thread overview]
Message-ID: <4B9B022F.6060402@shikadi.net> (raw)
Hi all,
I'm working on a USB HID driver, but my driver seems to be receiving bad data.
I think it's because usbhid_submit_report is non-blocking and I'm not
correctly waiting for a response. I'm not sure though, because none of the
existing usbhid drivers seem to work in this way.
Could someone please let me know if I'm going about this the right way?
odin_psu->report->field[0]->value[0] = msg;
odin_psu->report->field[0]->value[1] = 0x01;
usbhid_submit_report(odin_psu->hdev, odin_psu->report, USB_DIR_OUT);
usbhid_wait_io(odin_psu->hdev);
usbhid_submit_report(odin_psu->hdev, odin_psu->report_in, USB_DIR_IN);
usbhid_wait_io(odin_psu->hdev);
Many thanks,
Adam.
