Hi, I am using “3.1.0-7.fc16.x86_64” kernel and testing eight USB Bluetooth dongles using btusb.ko module. Once I power-on the system and loading the btusb.ko driver immediately results the below mentioned errors: [ 1389.410907] hci3 urb ffff88012954dd80 status -32 count 0 [ 1389.411367] hci4 urb ffff88012954d3c0 status -32 count 0 [ 1389.411845] hci1 urb ffff88012b4b6b40 status -32 count 0 [ 1389.412238] hci2 urb ffff8801347ee0c0 status -32 count 0 [ 1518.647255] hci3 urb ffff88012954dd80 status -32 count 0 [ 1518.647722] hci4 urb ffff88012954d3c0 status -32 count 0 [ 1518.648120] hci1 urb ffff88012b4b6b40 status -32 count 0 [ 1518.648514] hci2 urb ffff8801347ee0c0 status -32 count 0 [ 1518.722033] hci2 urb ffff8801347ee0c0 status -32 count 0 [ 2191.964545] hci4 urb ffff88012954d3c0 status -32 count 0 [ 2191.965001] hci1 urb ffff88012b4b6b40 status -32 count 0 [ 2191.965396] hci2 urb ffff8801347ee0c0 status -32 count 0 [ 2191.966530] hci2 urb ffff8801347ee0c0 status -32 count 0 [ 2191.975514] hci4 urb ffff88012954d3c0 status -32 count 0 [ 2191.975936] hci1 urb ffff88012b4b6b40 status -32 count 0 [ 2191.976330] hci2 urb ffff8801347ee0c0 status -32 count 0 [ 2191.977503] hci4 urb ffff88012954d3c0 status -32 count 0 [ 2191.977929] hci1 urb ffff88012b4b6b40 status -32 count 0 [ 2191.978325] hci2 urb ffff8801347ee0c0 status -32 count 0 [ 2560.132682] hci2 urb ffff8801347ee0c0 status -32 count 0 [ 2569.160895] hci4 urb ffff88012954d3c0 status -32 count 0 [ 2569.161367] hci1 urb ffff88012b4b6b40 status -32 count 0 [ 2569.161827] hci2 urb ffff8801347ee0c0 status -32 count 0 [ 3022.252541] hci2 urb ffff8801347ee0c0 status -32 count 0 [ 3022.254504] hci2 urb ffff8801347ee0c0 status -32 count 0 These errors will repeat until sending a proper HCI command on the USB bus. Again after some time duration same error will repeats. The error -32(-EPIPE) says , Endpoint stalled. For non-control endpoints, reset this status with usb_clear_halt(). But I don’t see the error(-EPIPE) handling code in btusb module. Does anyone has the patch for this scenario?
