Date: 21 Dec 2002 01:31:23 -0200 [thread overview]
Message-ID: <1040441486.3708.25.camel@beyond> (raw)
Hi,
I was trying to put my digital camera Olympus Brio Zoom D-150Zoom
to work on my RedHat 7.3 (2.4.18-3, redhat) when found this web page:
http://www.gingerbear.org/~esm/olympus/
Clicking on transport.c.diff link and taking a look into
/usr/src/linux-2.4.18-3/drivers/usb/storage/transport.c file
I started to ask my self what is doing the
if (bcs.Signature != cpu_to_le32(US_BULK_CS_SIGN) ||
statement there? Please if anyone could, answer me...
The patch applied to "support" this camera just remove this comparison,
so what it does?
Best regards,
Scorpion.
