confirm that single touch works with usbhid.quirks=0xeef:0x7356:0x40 appended to kernel. I read the thread and something is bugging me, what exactly is "usbhid.quirks=0xeef:0x7356:0x40" standing for, because I tried to build a custom kernel, and everything works well with this appended as kernel parameters, but I also built some modules for handling egalax touchscreen. It appears in 3.0-rc7 that hid-egalax was merged into hid-multitouch and it seems that this modules doesn't handle my egalax (0eef:7356 on a dell latitude e6420). I can't figure out what module exactly handles it because removing the kernel parameters, the touchscreen jump to the top left corner at any single touch on the screen. the only modules loaded at boot time by system are :
