DisplayLink USB 3.0 monitor on embedded linux
I'm working on an embedded linux platform (custom) ARM based.
The running kernel is: Code:
Linux 4.14.109-2.8.6 - armv7l Code:
- lsusb - Bus 005 Device 002: ID 17e9:ff10 DisplayLink Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 3.20 bDeviceClass 239 Miscellaneous Device bDeviceSubClass 2 bDeviceProtocol 1 Interface Association bMaxPacketSize0 9 idVendor 0x17e9 DisplayLink idProduct 0xff10 bcdDevice 31.03 iManufacturer 1 DisplayLink iProduct 2 I1659FWUX iSerial 3 GQQK2HA011233 bNumConfigurations 1 Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 90 bNumInterfaces 2 bConfigurationValue 1 iConfiguration 0 bmAttributes 0x80 (Bus Powered) MaxPower 126mA Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 bNumEndpoints 2 bInterfaceClass 255 Vendor Specific Class bInterfaceSubClass 0 bInterfaceProtocol 3 iInterface 0 ** UNRECOGNIZED: 0c 5f 01 00 0a 00 04 04 01 00 04 00 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x02 EP 2 OUT bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0400 1x 1024 bytes bInterval 0 bMaxBurst 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x84 EP 4 IN bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0400 1x 1024 bytes bInterval 0 bMaxBurst 0 Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 1 bAlternateSetting 0 bNumEndpoints 0 bInterfaceClass 254 Application Specific Interface bInterfaceSubClass 1 Device Firmware Update bInterfaceProtocol 1 iInterface 0 Device Firmware Upgrade Interface Descriptor: bLength 9 bDescriptorType 33 bmAttributes 1 Will Not Detach Manifestation Intolerant Upload Unsupported Download Supported wDetachTimeout 200 milliseconds wTransferSize 1024 bytes bcdDFUVersion 1.01 ** UNRECOGNIZED: 10 40 0a 00 36 08 0a 1a 46 66 6c 79 4d 6f 6e 69 Binary Object Store Descriptor: bLength 5 bDescriptorType 15 wTotalLength 70 bNumDeviceCaps 4 FIXME: alloc bigger buffer for device capability descriptors can't get debug descriptor: Resource temporarily unavailable Device Status: 0x0000 (Bus Powered) Is there a way to make the product working on this environment? |
