To reprogram TeleMega, it has to reboot to the boot loader, which
appears as a different device to Windows. Most of the time, things work
out just fine, but sometimes Windows gets confused by this. You should
leave TeleMega powered on, restart AltosUI and it should find the device
now at COM12 in boot loader mode and happily reflash from there.
