Thanks for the feedback Charles. I'll start snooping the stream in a Windows environment.
For what it's worth, we're having the same issue with a magnetic stripe reader from ID Innovations. Of special interest also, is that the report descriptors are unavailable. I'll post the results of the same commands in case it's helpful to anyone in a similar position. If I'm understanding you correctly, it sounds like the real solution is for the manufacturer to make changes to the firmware? Some information on the MSR exists here: http://idinnovations.com/downloads.html I can't seem to find their HID manual on that page, so I've posted it here: http://brent.izolo.com/tmp/HID.pdf ==> lsusb result: Bus 002 Device 008: ID 154a:0004 Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 1.10 bDeviceClass 0 (Defined at Interface level) bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 8 idVendor 0x154a idProduct 0x0004 bcdDevice 1.06 iManufacturer 1 ID Innovations Inc. iProduct 2 Magnetic Card Reader iSerial 0 bNumConfigurations 1 Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 59 bNumInterfaces 2 bConfigurationValue 1 iConfiguration 4 Input Device bmAttributes 0x80 MaxPower 100mA Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 bNumEndpoints 1 bInterfaceClass 3 Human Interface Devices bInterfaceSubClass 1 Boot Interface Subclass bInterfaceProtocol 1 Keyboard iInterface 5 HID Keyboard Interface HID Device Descriptor: bLength 9 bDescriptorType 33 bcdHID 1.00 bCountryCode 0 Not supported bNumDescriptors 1 bDescriptorType 34 Report wDescriptorLength 59 Report Descriptors: ** UNAVAILABLE ** Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x81 EP 1 IN bmAttributes 3 Transfer Type Interrupt Synch Type None Usage Type Data wMaxPacketSize 0x0008 1x 8 bytes bInterval 10 Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 1 bAlternateSetting 0 bNumEndpoints 1 bInterfaceClass 3 Human Interface Devices bInterfaceSubClass 0 No Subclass bInterfaceProtocol 0 None iInterface 6 Serial Interface HID Device Descriptor: bLength 9 bDescriptorType 33 bcdHID 1.00 bCountryCode 0 Not supported bNumDescriptors 1 bDescriptorType 34 Report wDescriptorLength 97 Report Descriptors: ** UNAVAILABLE ** Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x82 EP 2 IN bmAttributes 3 Transfer Type Interrupt Synch Type None Usage Type Data wMaxPacketSize 0x0008 1x 8 bytes bInterval 10 ==> libhid test: NOTICE: hid_init(): libhid 0.2.15+20060325.0.0 is being initialized.
