posted this on barry mailing list so will do it here also
for those who have the 8100 (dont remember if this is only one) with the new firmware upgrade from t-mobile bcharge and usb mass storage now work but btool for backup does not work unless you run bcharge twice and second time with -o switch. also now works with vmware so you can use windows to backup upgrade and all those good things if you have vmware.
so if you can get to a windows box and upgrade
long story short dont have ub in the kernel or it get greedy and does not let go :o but now for the people who where having the 2 endpoint issue it should be fixed
want to use btool? just rmmod usb_storage and if you want the sd card available again just modprobe it
