Oh, sorry, I didn't see this email, and actually there is no need for replug it,
every time I met this problem, simply restart the pcscd can solve it.

Meanwhile the kernel said:
May 23 19:56:07 kernel: xhci_hcd 0000:05:00.2: xHC error in resume, USBSTS 0x401, Reinit

So may it caused by the buggy XHCI controller dropped the first 3 test command packets?
Whatever, this is a simply and rude solution:
```
[Service]
Restart=on-failure
RestartSec=30s
```
