From mboxrd@z Thu Jan 1 00:00:00 1970 From: Andrey Borzenkov Date: Sun, 09 Nov 2003 18:55:19 +0000 Subject: file2alias - incorrect? aliases for USB Message-Id: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-hotplug@vger.kernel.org file2aliases puts in alias device ID high and low numbers directly from match specifications. E.g. for this match table entry: usb-storage 0x000f 0x04e6 0x0006 0x0100 0x0205 ... it generates alias alias usb:v04E6p0006dl0100dh0205dc*dsc*dp*ic*isc*ip* usb_storage unfortunately real device attribute does not include high and low - rather it has single device ID (as part of PRODUCT) that should be contained in these bounds: length += snprintf (scratch, buffer_size - length, "PRODUCT=%x/%x/%x", usb_dev->descriptor.idVendor, usb_dev->descriptor.idProduct, usb_dev->descriptor.bcdDevice); or bcdDevice file in sysfs. This makes those aliases rather useless for the purpose of matching reported device. It may take the same route as PCI and reject all device ID table entries that have High != Low but there are quite a few of them available. I am rather confused because I do not see how this condition (low <= bcdDevice <= high) can be expressed using simple glob pattern (unless we are going to take glob library from Zsh :) thank you -andrey ------------------------------------------------------- This SF.Net email sponsored by: ApacheCon 2003, 16-19 November in Las Vegas.
