Subject: [PATCH] USB: serial: pl2303: fix GT type detection
Date: Wed, 4 Aug 2021 11:31:00 +0200 [thread overview]
Message-ID: <20210804093100.24811-1-johan@kernel.org> (raw)
In-Reply-To: <YQpeE19WIeQO2b//@hovoldconsulting.com>
At least some PL2303GT have a bcdDevice of 0x305 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")
