Title: pl2303 serial adapter not recognized Status in linux package in Ubuntu: Incomplete Status in linux source package in Impish: New Status in linux source package in Jammy: New Status in linux source package in Kinetic: Incomplete Bug description: Hi After upgrading the Linux kernel from 5.11.0-27 to 5.13.0-37 a device that uses a pl2303 usb serial chip no longer works. This seems very similar to bug 1959110, and according to that it should be fixed, but somehow it's not. # uname -a Linux GAU233333LD04 5.13.0-37-generic #42~20.04.1-Ubuntu SMP Tue Mar 15 15:44:28 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux # journalctl -b -k -g pl2303 -o cat usbcore: registered new interface driver pl2303 usbserial: USB Serial support registered for pl2303 pl2303 1-12:1.0: pl2303 converter detected pl2303 1-12:1.0: unknown device type, please report to linux-...@vger.kernel.org # udevadm info /sys/devices/pci0000:00/0000:00:14.0/usb1/1-12/1-12:1.0 P: /devices/pci0000:00/0000:00:14.0/usb1/1-12/1-12:1.0 L: 0 E: DEVPATH=/devices/pci0000:00/0000:00:14.0/usb1/1-12/1-12:1.0 E: DEVTYPE=usb_interface E: PRODUCT=67b/2303/300 E: TYPE=0/0/0 E: INTERFACE=255/0/0 E: MODALIAS=usb:v067Bp2303d0300dc00dsc00dp00icFFisc00ip00in00 E: SUBSYSTEM=usb E: USEC_INITIALIZED=56177916 E: ID_VENDOR_FROM_DATABASE=Prolific Technology, Inc.
