Hi, I am facing problems with my USB Device driver while resuming from suspend state. The Controller and the stack on my PC is ehci-hcd and the device is a High speed wireless interface. I have unloaded usb-uhci so that the device is managed by EHCI stack only. When the system comes back to resume state then there is no activity to reset/restart the device. Once coming back from suspend state the device is not recognized by the stack at all. Even if I plug out the device and plug it back again the USB stack doesn't report any device insertion.
I tried to do suspend of the system without loading my driver. When the device is inserted before I suspend the system does report "New Device Insertion" but after coming to resume state the system doesn't report any "New Device Insertion". I am using APM driver for power management. The command to suspend is "apm -s". The kernel I am testing on is "2.4.22-1.2115.nptl" from Redhat Fedora Core 1. I have also tested on Redhat 9 (Kernel 2.4.20-8) and results are same. Is this a known issue with USB EHCI stack or am I doing something wrong? If there is some error on my side then please help me in rectifying it. If this is some known issue then is this documented somewhere? Regards.
