I'm trying to use 2.6.28 for the first time on an x86_64 box here with devices controlled by libusb. The devices work on the first access, but then fail on all subsequent accesses. Unplugging/replugging causes them to work again for a single subsequent access. This is with two completely different USB gadgets: a VFD alphanumeric display, and an FTDI serial device in bitbang mode. Did something break in 2.6.28 for libusb devices ??
.. Mmm.. broken only for 64-bit userspace, it seems. I've recompiled the same app against 32-bit libs, and it works just fine on that 64-bit system, as well as on 32-bit systems. But not when compiled for pure 64-bit operation on a 64-bit system. Looks tricky .. must be a change somewhere that assumes a pointer/long is 32-bits or something. -ml -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
