From cc3b5159227b352be1196922fcb94266c1a1904a Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Tue, 23 Nov 2021 10:10:17 +0100 Subject: [PATCH] USB: serial: pl2303: fix GC type detection At least some PL2303GC have a bcdDevice of 0x105 instead of 0x100 as the datasheet claims. Add it to the list of known release numbers for the HXN (G) type. Note the chip type could only be determined indirectly based on its package being of QFP type, which appears to only be available for PL2303GC.
