Macleg Posted May 27, 2023 Share Posted May 27, 2023 Hello! First time poster to the forums, appreciate anyone who manages to read this! I have a UnRAID install with Home Assistant as a VM currently, but looking to move that to a Docker Container for the challenge/Learning opportunity of it but having issues with device pass through. This is an optional activity, but I'd love to learn why I'm stuck. When I do the command "lsusb" I get the a number of devices, but the one I want to use is here: Bus 001 Device 004: ID 0bda:2838 Realtek Semiconductor Corp. RTL2838 DVB-T However when I do: "ls -l /dev/serial/by-id" I do not see the device, insetad I only see my Zigbee dongle here, no signs of the SDR: lrwxrwxrwx 1 root root 13 May 26 13:57 usb-ITead_Sonoff_Zigbee_3.0_USB_Dongle_Plus_cxxxxxxxxxxxxxxxxxxxx-if00-port0 -> ../../ttyUSB0 Finally, trying the following lsusb -v -s 001:004 based on the bus and device, I get an output of the following: Bus 001 Device 004: ID 0bda:2838 Realtek Semiconductor Corp. RTL2838 DVB-T Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 2.00 bDeviceClass 0 bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 64 idVendor 0x0bda Realtek Semiconductor Corp. idProduct 0x2838 RTL2838 DVB-T bcdDevice 1.00 iManufacturer 1 Realtek iProduct 2 RTL2838UHIDIR iSerial 3 00000001 bNumConfigurations 1 Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 0x0022 bNumInterfaces 2 bConfigurationValue 1 iConfiguration 4 USB2.0-Bulk&Iso bmAttributes 0x80 (Bus Powered) MaxPower 500mA Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 bNumEndpoints 1 bInterfaceClass 255 Vendor Specific Class bInterfaceSubClass 255 Vendor Specific Subclass bInterfaceProtocol 255 Vendor Specific Protocol iInterface 5 Bulk-In, Interface Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x81 EP 1 IN bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0200 1x 512 bytes bInterval 0 Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 1 bAlternateSetting 0 bNumEndpoints 0 bInterfaceClass 255 Vendor Specific Class bInterfaceSubClass 255 Vendor Specific Subclass bInterfaceProtocol 255 Vendor Specific Protocol iInterface 5 Bulk-In, Interface Device Qualifier (for other device speed): bLength 10 bDescriptorType 6 bcdUSB 2.00 bDeviceClass 0 bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 64 bNumConfigurations 2 Device Status: 0x0000 (Bus Powered) I guess what I'm trying to figure out is a) how to assign the device to my Home Assistant Container b) what is the device path I'd have to use to do it? For example in Zigbee2MQTT I have /dev/serial/by-id/usb-ITead_Sonoff_Zigbee_3.0_USB_Dongle_Plus_cxxxxxxxxxxxxxxxxxxxxx-if00-port0. I'm just not sure what that would equate to for my SDR dongle. Any thoughts? Am I tackling this incorrectly? Thanks! Quote Link to comment

You can us /dev/bus/usb/001/004 issue you will have is that the device numbers will may change i.e. if the device is reset etc. Quote Link to comment

Any thoughts possibly on my the Zigbee dongle would show up, but not the SDR? Quote Link to comment

Zigbee is a serial port Sdr is not. Only certain types report byid serial and storage. You may be able to create a udev rule to create a name to use. Quote Link to comment
