Subject: usb-storage and casio qv-4000 digital camera
Date: Mon, 8 Oct 2001 02:44:40 +0200 [thread overview]
Message-ID: <20011008024440.A1242@gondor.com> (raw)
(this is against linux-2.4.10-ac8, but should apply to kernels
with similar usb drivers, too)
The casio qv-4000 digital cameras needs the same workarounds
in usb-storage as older casio cameras, but has a different
serial number. Therefore the attached patch is needed to make
the camera work - otherwise, I get a lot of
"usb_control/bulk_msg: timeout" messages and the device doesn't work.
I think these are the corresponding lines in /proc/bus/usb/devices:
T: Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 3 Spd=12 MxCh= 0
D: Ver= 1.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1
P: Vendor=07cf ProdID=1001 Rev=10.00
C:* #Ifs= 1 Cfg#= 1 Atr=40 MxPwr= 0mA
I: If#= 0 Alt= 0 #EPs= 3 Cls=08(stor.) Sub=05 Prot=00 Driver=usb-storage
E: Ad=81(I) Atr=02(Bulk) MxPS= 64 Ivl= 0ms
E: Ad=02(O) Atr=02(Bulk) MxPS= 64 Ivl= 0ms
E: Ad=83(I) Atr=03(Int.) MxPS= 8 Ivl= 1ms
As the patch enables the workaround for a fairly huge range of revision
numbers, it may be better to have two distinct lines with smaller
ranges instead of one bug range - I leave this decision to people
who know more about USB than I do ;-)
