lsusb -v cdc device #67

Closed SeenTwo closed 1 year ago

SeenTwo commented 1 year ago

Every time I do this on Linux: lsusb -v

Then a log appears on my device:

[E/USB] descriptor <type:6,index:0> not found!
[E/USB] standard request error

On Linux, this is the output of my device:

  (Bus Powered)

The project has a device qualifier descriptor and define CONFIG_USB_HS:

#ifdef CONFIG_USB_HS
    ///////////////////////////////////////
    /// device qualifier descriptor
    ///////////////////////////////////////
    0x0a,
    USB_DESCRIPTOR_TYPE_DEVICE_QUALIFIER,

    0x01,
    0x40,
    0x01,
    0x00,
#endif
    0x00

In fact, I did not change anything in the descriptor, except for: vid, pid and 3 string . The sizes of string correctly counted

sakumisu commented 1 year ago

It is impossible to print this log forever.

sakumisu commented 1 year ago

If you use high speed, you must define CONFIG_USB_HS

sakumisu commented 1 year ago

Please check with cdc_acm_template.c , it works, thank you! Try yourself again!

SeenTwo commented 1 year ago

define CONFIG_USB_HS - yes. In IDE highlights what is defined. In build console shows: -DCONFIG_USB_HS. Linux: kernel 5.4.0-132-generic, Kubuntu 20.04 Device: ch32v307. string3 descriptor is uid device hex 24 symbols.

I also tried changing vid and pid. Problem still exists

SeenTwo commented 1 year ago

I copied the cdc_acm_template.c example into my project, the problem is slightly different. Now when I call lsusb -v, I see one message in the debug messages of the device: [E/USB] standard request error

On Linux, the output of lsusb has now changed:

Is there something wrong with my descriptor?

SeenTwo commented 1 year ago

I'm blind. The size of string3 was calculated incorrectly. Everything works now. It remains to solve the problem: debug descriptor. But this topic is no longer relevant.

sakumisu commented 1 year ago

Please disable other speed in device quality descriptor, bNumConfigurations should be 0.
