Hello everyone,
I'd like to encrypt my external HDD using dm-crypt (luks) via USB 3.0.
The crypto-container creation works, but writing to it doesn't:

USB 2.0 (ehci-pci) works fine (direct, filesystem, crypto). With USB
3.0, both direct access using 'dd' and filesystem access is possible.
Only direct access to the cryptdevice fails (including 'mkfs.ext4').
If I create a filesystem on the crypto device via USB 2.0, I can access
it via USB 3.0 as well.

See [1] for a journalctl-log with xhci-debugging enabled. I also made an
usbmon-trace [2].
