CC r43224 / ARV752DPW22 / 2 of 3 USB ports doesn't work

[gho@…]

Putting a device into the left and lower rear port doesn't show any reaction (either kernel log nor hotplug). The upper rear port (originally for a 3g dongle) does...

... the "Bus 001 Device 001" seems to be the hub with the two ports not working.

Two rear buttons ("Restart" and "?") are also functionless at the moment.

Image was build with Image Builder.

Hello folks... what can I further do to approach the problem?

#18287 sounds similar

So ifxusb works - ehci doesn't.

How can I get more log information from ehci driver?

[gho@…]

dsdwn, can you confirm this issue?

[anonymous]

I can confirm an issue, even with latest Chaos Calmer.

I have this router. I have compiled trunk in august 2014 and all usb ports worked. Trunk of Dec 2014 had this problem. Please advise if I can help pinpoint the probelm better. I have just bought two new routers like this and I am about to try installing the latest trunk on them. Will report later

[gho@…]

Getting news on this with 15RC1 or latest trunk would be helpful.

Only port dedicated for modem (this on top of device) works. On 2nd easybox with 14.x on it lspci shows also usb 1.1 hubs.

[guraltsev]

This is still the case in r48016. Can I do something to help?

[info@…]

I can confirm an issue, but 0400-fix-IO_SPACE_LIMIT-constant.patch Ticket 20997 und 0401-fix-irq-chip-for-exins.patch​ Ticket 21318 resolve this problem.

All works (USB Port left):

Still an issue also with latest trunk (with output as in comment 13).

A very old ticket so it would be HIGHLY appreciated if this could be fixed finally.

[anonymous]

As far as I can see, both patches fix bugs in the linux kernel and not OpenWrt specific bugs. The patches need to be send to the ​Linux MIPS mailinglist (since they touch the mips specific part of the kernel) for inclusion into the linux kernel.

If they are included in the linux kernel, they can be send as backport to the ​OpenWrt Development Mailinglist.

As long as the patch author doesn't go the outlined way, the bug will be presumably never fixed and it's required to apply the patches to OpenWrt and compile from source all the time.

Master branch of Linux/MIPS repository recently had some changes on irq.c that could finally address this issue.
