Hubs not working in 3.2 kernel, Super Zaxxon 1.51

[bismuthdrummer]

I have two hubs, tested and working under other machines and in the old 2.6 kernel but not in the latest 3.2 kernel. I plug in the hub, it shows up in dmesg, then I plug in any device (mouse, keyboard, flash drive, etc.) and I get the USB disconnect crash issue that happens when you plug a non-2.0-compatible device directly into the back.


dmesg usb | tail

Is this a known bug for SZ 1.51? If not can anyone replicate this?

It's a broken driver, OMAP USB support is in a poor state. Plugging the devices to hub first and then hub to pandora usually helps, but you need to reboot when it's in bad state to recover, or at least do "sudo rmmod ehci_hcd; sudo modprove ehci_hcd"

Ah ok, plugging it in with one device attached made it plug-and-play as normal.


Sucks for the OMAP support, we must clone you! I am sure you get that a lot.


Thanks.
