rpi3b+ usb issues since kernel 6.5.5

Postby df8oe » Fri Sep 29, 2023 11:50 am

I have a working hardware configuration where all USB ports on my rpi are used. One is connected to a 4-USB-hub where two small devices are connected - all running since years.

Starting with kernel 6.5.5 there must be a test for "USB powered devices" and most of my connected devices are no longer supported. The dmesg-messages are:

usb 1-1.2: can't connect bus-powered hub to this port Hub
and
usb 1-1.4: rejected 1 configuration due to insufficient available bus power

Does anyone have a hint to disable this tests via cmdline? They are bothering with false-positives...

Are you building your own kernel or using my testing linux-rpi kernel?

I am using your testing linux-rpi kernel. In the meantime I found a workaround which solves the issue and which is neccessary since 6.5.5:

add this line to "config.txt":

max_usb_current=1

Recommend you open a ticket upstream:make_clickable_callback(MAGIC_URL_FULL, ' ', 'https://github.com/raspberrypi/linux/issues', '', ' class="postlink"')

EDIT:
Is it possible to bring forum markups again to work?
