Patch for 2.6.9.18-rc6 to add support for Alcor Micro Corp. USB 2.0 TO RS-232 converter. This patch adds VID and PID to pl2303.[ch], adds it to the "HORRIBLE HACK FOR PL2303" in usb-serial.c and also prevents cdc-acm to claim driving this device by blacklisting it in hid-core.
Signed-off-by: Johannes Steingraeber <[EMAIL PROTECTED]> --- Stephen HippisleyCox ( s.d.hippisley-cox <at> ntlworld <dot> com ) first discovered and mentioned that this device has a pl2303 inside. http://www.qbik.ch/usb/devices/showdev.php?id=3846 I first had trouble with a similar device but then made it working with this patch. --- linux-2.6.18-rc6/drivers/usb/input/hid-core.c.orig 2006-09-04 04:19:48.000000000 +0200 +++ linux-2.6.18-rc6/drivers/usb/input/hid-core.c 2006-09-08 21:43:13.000000000 +0200 @@ -1591,6 +1591,10 @@ void hid_init_reports(struct hid_device #define USB_VENDOR_ID_YEALINK 0x6993 #define USB_DEVICE_ID_YEALINK_P1K_P4K_B2K 0xb001 + +#define USB_VENDOR_ID_ALCOR 0x058f +#define USB_DEVICE_ID_ALCOR_USBRS232 0x9720 + /* * Alphabetically sorted blacklist by quirk type. */ @@ -1608,6 +1612,7 @@ static const struct hid_blacklist { { USB_VENDOR_ID_AIPTEK, USB_DEVICE_ID_AIPTEK_22, HID_QUIRK_IGNORE }, { USB_VENDOR_ID_AIPTEK, USB_DEVICE_ID_AIPTEK_23, HID_QUIRK_IGNORE }, { USB_VENDOR_ID_AIPTEK, USB_DEVICE_ID_AIPTEK_24, HID_QUIRK_IGNORE }, + { USB_VENDOR_ID_ALCOR, USB_DEVICE_ID_ALCOR_USBRS232, HID_QUIRK_IGNORE }, { USB_VENDOR_ID_BERKSHIRE, USB_DEVICE_ID_BERKSHIRE_PCWD, HID_QUIRK_IGNORE }, { USB_VENDOR_ID_CODEMERCS, USB_DEVICE_ID_CODEMERCS_IOW40, HID_QUIRK_IGNORE }, { USB_VENDOR_ID_CODEMERCS, USB_DEVICE_ID_CODEMERCS_IOW24, HID_QUIRK_IGNORE }, --- linux-2.6.18-rc6/drivers/usb/serial/usb-serial.c.orig 2006-09-04 04:19:48.000000000 +0200 +++ linux-2.6.18-rc6/drivers/usb/serial/usb-serial.c 2006-09-08 21:48:07.000000000 +0200 @@ -714,7 +714,9 @@ int usb_serial_probe(struct usb_interfac if (((le16_to_cpu(dev->descriptor.idVendor) == PL2303_VENDOR_ID) && (le16_to_cpu(dev->descriptor.idProduct) == PL2303_PRODUCT_ID)) || ((le16_to_cpu(dev->descriptor.idVendor) == ATEN_VENDOR_ID) && - (le16_to_cpu(dev->descriptor.idProduct) == ATEN_PRODUCT_ID))) { + (le16_to_cpu(dev->descriptor.idProduct) == ATEN_PRODUCT_ID)) || + ((le16_to_cpu(dev->descriptor.idVendor) == ALCOR_VENDOR_ID) && + (le16_to_cpu(dev->descriptor.idProduct) == ALCOR_PRODUCT_ID))) { if (interface != dev->actconfig->interface[0]) { /* check out the endpoints of the other interface*/ iface_desc = dev->actconfig->interface[0]->cur_altsetting; --- linux-2.6.18-rc6/drivers/usb/serial/pl2303.h.orig 2006-09-04 04:19:48.000000000 +0200 +++ linux-2.6.18-rc6/drivers/usb/serial/pl2303.h 2006-09-08 21:44:51.000000000 +0200 @@ -89,3 +89,7 @@ /* Belkin "F5U257" Serial Adapter */ #define BELKIN_VENDOR_ID 0x050d #define BELKIN_PRODUCT_ID 0x0257 + +/* Alcor Micro Corp.
