Hi
We have a Cashino PTP-lil/BT24 Slip printer[1]. When configured in
serial mode, it uses a pl2303 chip. This has not detected by the
kernel since 5.13. The bcdUSB is 1.01, and the driver was changed to
only allow 1.10 and 2.00 [2] Please consider adding 1.01 as an
allowed pl2303 bcdUSB.
Thanks, Gary

Heh. USB 1.01? I'll add a workaround to continue treating this as 1.10
(and an HX device).
Can I credit you using name and email in the commit message for
reporting this?
