Subject: MAX_USBFS_BUFFER_SIZE
Date: Wed, 1 Mar 2006 21:16:25 +0100	[thread overview]
Message-ID: <200603012116.25869.rene@exactcode.de> (raw)

Hi,

I wonder if:

drivers/usb/core/devio.c:86
#define MAX_USBFS_BUFFER_SIZE   16384

is some random, or outdated limit or if there really is some code path that could
not handle bigger URBs.

For performance reasons I would like to use bigger packages for an image
aquisition device.

Yours,
