QUESTION

Issue with debugging usb using usbmon

Asked 2021-May-31 at 08:09

I am using Linux 4.19.55 armv7l on a omap3 processor. On my target there is a usb modem that gets power from a gpio pin value (defined under /sys/class/gpio). There are occasions when I change the value parameter of this gpio pin to bring down the hardware and while doing so I frequently get an error (thrown by musb_handle_intr_disconnect from inside drivers/usb/musb/musb_core.c ) as under:

"musb_handle_intr_disconnect 843: unhandled DISCONNECT transition (a_idle)"

I tried debugging the issue by mounting debugfs and capturing data from the concerned bus by using usbmon. Bus id is identified from lsusb output and confirmed by observing /sys/kernel/debug/usb/devices. I observe that usbmon is unable to capture data whenever the mentioned error shows up. In a no error scenario the usbmon does capture the traffic from the concerned bus. Please help how to debug this issue.

Just checked that a commit on kernel branch fixes this issue which is present inside the states handled by the glue layer. This is the required commit

QUESTION

Minimal Linux kernel options to enable hid input

Asked 2020-Nov-04 at 08:20

I need to handle a HID device (a barcode reader) with a custom Linux (v5.8).

I have a modulerized kernel which works as expected with other USB peripherals (storage and serial are known to work), but I seem unable to scan this device.

Plugging it into a desktop (Linux Mint "Ulyana", if it matters) I get a normal enumeration:

It turns out OHCI driver is needed to handle low speed peripherals even if they're connected to USB2 (EHCI) controller.

Actually MT7628 has a "secondary" OHCI controller not even advertised in Data Sheet.

This means that, on top of selecting CONFIG_USB_OHCI_HCD=m and CONFIG_USB_OHCI_HCD_PLATFORM=m also the following patch is needed:

QUESTION

CubeMX-generated USB HID device sends wrong data when both endpoint and PMA address are changed

Asked 2020-Jan-29 at 16:32

I'm debugging a problem with a composite device that I'm creating, and have recreated the issue in freshly-CubeMX-generated HID-only code, to make it easier to resolve.

I've added small amount of code to main() to let me send USB HID mouse-clicks, and flash an LED, when the blue-button is pressed.
