Not working properly #76
Comments

Have you tried the FunctionFs mode instead ? |
|
Hi, Whenever umtprd is exited, I get this crash. I have seen it on 1.3.10 version. I upgraded to 1.6.2 version hoping it might resolve the issue and now it doesn't enumerate on bootup. If I manually try starting umtprd from the command line, it starts ok, but it does not enumerate on the Windows side with an invalid device descriptor error. On 1.3.10 it enumerates ok, but on both versions I see this crash when umtprd is exited. Below is console output with debug on and dmesg output: May 16 16:05:00 PLMOS user.notice umtprd: [uMTPrd - Info] uMTP Responder [ 401.213387] USB cable disconnected - dwc3 pullups_connected=false |
|
I see that you are using dwc3. Have you enabled "CONFIG_USB_SS_SUPPORT" in "buildconf.h" ? |
|
If this still doesn't work with the CONFIG_USB_SS_SUPPORT enabled, try to disable the inotify support in the umtp config file. |
|
Yes, we are using dwc3....our device is an embedded system running Linux
and the USB hardware only supports Hi-Speed so we are set to that speed. I
have tried with both CONFIG_USB_SS_SUPPORT enabled and not enabled and it
did not make a difference probably since we are just using Hi-Speed with
dwc3. I also changed the umtprd.conf fle to disable inotify and that also
did not make any difference. Our device does not enumerate with Windows
after upgrading to 1.6.2 and when exiting umtprd, the kernel WARNING at
dwc3_stop_active_transfer still appears. Any ideas of what to try or what
may be causing both of these issues?
