It seems that usb-utils.tcz as in tc-4.x and tc-5.x has undergone a name change to usbutils.tcz in tc-6.x recently.
usb-utils.tcz is a required dep of at least three extensions that I know of, which of course prevents APPS from download those extensions now..
not sure if this is a typo, are we missing the " - " ?? if the name change was planned then maybe the deps files which request usb-utils.tcz need changing..?
thanks
