Hello Toradex Community,
we have designed a PCB using a Colibri iMX6 SoC and an USB hub. The hub is directly powered by 5V and is configured via I2C.
In rare cases, it happens that the device is rejected in Linux because of bus power limitations. The cause is unknown to us (it does not always happen).
We tried to use the information from this site: USB: rejected 1 configuration due to insufficient available bus power | /contrib/famzah
This does not always work unfortunately.
So, is there a way to tell the system to not check the power limitations but always accept the device?
We use a customized Toradex Linux, so any hint regarding kernel configuration, kernel boot parameters or even device tree customization to achieve this would be helpful.
Thank you in advance!
