Subject: Bug report: pl2303 unknown device type -
Date: Mon, 16 May 2022 19:48:51 +0200 [thread overview]
Message-ID: <CAJixRzqf4a9-ZKZDgWxicc_BpfdZVE9qqGmkiO7xEstOXUbGvQ@mail.gmail.com> (raw)
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
