[PATCH v2 0/3] CanoKey: Fix xHCI compatibility and CCID ZLP

["Hongren (Zenithal) Zheng" <i@zenithal.me>]

In patch v5 [1] of Introduce CanoKey QEMU I said that canokey-qemu
was incompatible with qemu-xhci.

kraxel kindly suggested[2] that it should be the problem of usb_wakeup
So I fixed it in this patch set.

Now that the v5 patch has been in the process of git PULL [3],
I think it would be better to post a new patch set instead
of sending out v6, which would make maintainer's tree back and forth.

This patch should be applied after [1].

As for the CCID ZLP issue, it is described in the comment and commit
message.

I added a commit in https://github.com/canokeys/canokey-qemu
to export the EP num in the header, so hw/usb/canokey.c in qemu
could use it for CTAPHID quirks. If you want to compile
this version when --enable-canokey, make sure to use the latest
libcanokey-qemu.so

The CI result for this PATCH is at [4]. The failure for
amd64-debian-container seems irrelevent to this patchset.
