From: Mikhail Peselnik <peselnik@xxxxxxxxx> This patch adds support for PL-2501 by adding the appropriate USB ID's. This chip is used in several USB 'Easy Trasfer' Cables. Signed-off-by: Mikhail Peselnik <peselnik@xxxxxxxxx> Tested-by: Mikhail Peselnik <peselnik@xxxxxxxxx> --- Now with proper sign-offs and right people in cc and unwrapped lines. plusb driver (drivers/net/usb/plusb.c) doesn't recognize PL2501 chip. Since PL2501 uses the same code as PL2301/PL2302 (PL2501 works in compatibility mode with PL2301/PL2302), the fix is trivial and attached as a patch. Just to note: the patch is not mine, it can be found here and there on Internet. I've tested the patch and it works great. Thank you. --- linux-3.5/drivers/net/usb/plusb.c.orig 2012-07-22 21:06:41.905802795 +0400 +++ linux-3.5/drivers/net/usb/plusb.c 2012-07-22 21:07:00.345552404 +0400 @@ -107,7 +107,7 @@ static int pl_reset(struct usbnet *dev) } static const struct driver_info prolific_info = { - .description = "Prolific PL-2301/PL-2302/PL-25A1", + .description = "Prolific PL-2301/PL-2302/PL-25A1/PL-2501", .flags = FLAG_POINTTOPOINT | FLAG_NO_SETINT, /* some PL-2302 versions seem to fail usb_set_interface() */ .reset = pl_reset, @@ -139,6 +139,9 @@ static const struct usb_device_id produc }, { USB_DEVICE(0x050d, 0x258a), /* Belkin F5U258/F5U279 (PL-25A1) */ .driver_info = (unsigned long) &prolific_info, +}, { + USB_DEVICE(0x067b, 0x2501), /* PL-2501 */ + .driver_info = (unsigned long) &prolific_info, }, { }, // END @@ -158,5 +161,5 @@ static struct usb_driver plusb_driver = module_usb_driver(plusb_driver); MODULE_AUTHOR("David Brownell"); -MODULE_DESCRIPTION("Prolific PL-2301/2302/25A1 USB Host to Host Link Driver"); +MODULE_DESCRIPTION("Prolific PL-2301/2302/25A1/2501 USB Host to Host Link Driver"); MODULE_LICENSE("GPL"); -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
