I try to connect specific vendor usb 3.0 camera. I have api with 3 endpoints and one of them get image (ENDPOINT 0x86). After some time of receiving image, libusb return timeout error. There’re different times for receiving error on different cables (1 - 150-200 frames, 2 - 9000 - 12000 frames). I tried command
dmesg to show log, when connect the camera. In Tk1 i see:
Parent Hub missing LPM exit latency info. Power management will be impacted.
I also tried to connect camera to x86 PC with Ubuntu 18.0.4 LTS and there are evything is ok, but as i understand from
dmesg, it automatically disable LPM:
LPM exit latency is zeroed, disabling LPM.
So, i think i need to disable LPM fot this usb 3.0. device manually. How iiit possible to make on Ubuntu for TK1?
