Subject: [PATCH] USB: serial: pl2303: fix GL type detection
Date: Thu, 26 Aug 2021 13:02:39 +0200 [thread overview]
Message-ID: <20210826110239.5269-1-robert.marko@sartura.hr> (raw)
At least some PL2303GL have a bcdDevice of 0x405 instead of 0x100 as the
datasheet claims. Add it to the list of known release numbers for the
HXN (G) type.
Fixes: 894758d0571d ("USB: serial: pl2303: tighten type HXN (G) detection")
