Some people still have problem with their touchscreen when installing whatever custom ROM, including this one. When faced with this, mouse or keyboard from usb port could come handy, but the default mode for usb in this build is "peripheral", which means: no mouse, or keyboard will be recognized at the usb port.
Enabling usb host mode is easy using shuttle tool, but frustrating when you don't have your touchscreen work. So, maybe it's better to set it to host mode by default.
In Vegacream beta 2.1 you can use this approach I post earlier, but in vegabean you cannot. You'll need to remount your /system read+write enabled in order to do that, so:
1. Open Terminal Emulator
2. Enter the following:
xx@anroid:/$ mount -o remount,rw /system
xx@anroid:/$ echo "echo 1 > /sys/usbbus/host_mode" >> /etc/vega_postboot.sh
xx@anroid:/$ mount - remount,ro /system
reboot your tablet with the host mode enabled by default.
Any problem, please comment away!
