Howdy Johan, Thanks very much for the patch; I tested your branch with my Carelink stick and it works sometimes. Here's an example of it working as expected: Mar 17 16:51:08 patient logger: Linux patient 3.14.0-rc6-bewest-test-carelink-01 #5 SMP Mon Mar 17 15:32:48 PDT 2014 x86_64 x86_64 x86_64 GNU/Linux Mar 17 16:51:15 patient kernel: [ 1304.065633] usb 3-1: new full-speed USB device number 9 using xhci_hcd Mar 17 16:51:15 patient kernel: [ 1304.195494] usb 3-1: New USB device found, idVendor=0a21, idProduct=8001 Mar 17 16:51:15 patient kernel: [ 1304.195498] usb 3-1: New USB device strings: Mfr=0, Product=0, SerialNumber=0 Mar 17 16:51:15 patient kernel: [ 1304.196137] usb_serial_simple 3-1:1.0: carelink converter detected Mar 17 16:51:15 patient kernel: [ 1304.196242] usb 3-1: carelink converter now attached to ttyUSB0 Mar 17 16:51:15 patient mtp-probe: checking bus 3, device 9: "/sys/devices/pci0000:00/0000:00:14.0/usb3/3-1" Mar 17 16:51:15 patient mtp-probe: bus: 3, device: 9 was not an MTP device And I was able to use the created device. However, most of the time, I get this: Mar 17 23:19:38 patient logger: Linux patient 3.14.0-rc6-bewest-test-carelink-01 #5 SMP Mon Mar 17 15:32:48 PDT 2014 x86_64 x86_64 x86_64 GNU/Linux Mar 17 23:20:12 patient testing-carelink: inserting carelink stick in first port Mar 17 23:20:20 patient kernel: [24640.467545] usb 3-1: new full-speed USB device number 35 using xhci_hcd Mar 17 23:20:25 patient kernel: [24645.577653] xhci_hcd 0000:00:14.0: Timeout while waiting for setup address command Mar 17 23:20:30 patient whoopsie[1258]: online Mar 17 23:20:30 patient kernel: [24650.779769] xhci_hcd 0000:00:14.0: Timeout while waiting for setup address command Mar 17 23:20:30 patient kernel: [24650.983694] usb 3-1: device not accepting address 35, error -62 Mar 17 23:20:30 patient kernel: [24651.095691] usb 3-1: new full-speed USB device number 36 using xhci_hcd Mar 17 23:20:31 patient whoopsie[1258]: online Mar 17 23:20:41 patient whoopsie[1258]: online Mar 17 23:20:45 patient kernel: [24666.202282] usb 3-1: device descriptor read/64, error -110 Mar 17 23:20:46 patient kernel: [24666.306135] xhci_hcd 0000:00:14.0: Setup ERROR: setup context command for slot 5.
