At some point, this started working after a kernel/firmware update, so it's not really a valid question any more (or else, the solution is "update your RPi")
I have a Raspberry Pi Model B running Raspbian, and I have an EDIMAX wireless adapter as well as an IOGEAR USB mouse. Both of them work fine when they are connected individually; however, if I connect them both at once, the mouse does not work at all, even though it is detected during boot and there are not any error messages. Both devices are connected to a self-powered USB hub.
I read something that said the RPi had problems when both a high and low speed device were connected at the same time, but there was a possible fix with a newer kernel/firmware. I have updated to the latest kernel and firmware using
rpi-update, but the problem still exists. I also tried another suggestion which was plugging one device into the hub and the other directly into the RPi, but still no luck.
Is there something else I can try to get both of these working at the same time?

lsusbwhether it is working or not. The mouse is also detected and the driver is loaded the same way in
dmesg; however, when the WiFi adapter is connected as well, once everything has loaded it then displays a message saying "USB disconnect, device number 5" (which is the mouse) and then loads it all over again as a new device.
