Both Vendor and product id are ok.

[ 1075.879920] usb 1-1.2: SerialNumber: 06001069 To make it work you have to recompile the module pl2303, with this patch (my kernel is 2.6.35.10-74.fc14.i686). Be careful to setup the right values in the kernel root Makefile in order to fit your running kernel. *** drivers/usb/serial/pl2303.h.orig 2011-01-21 09:11:21.000000000 +0100 --- drivers/usb/serial/pl2303.h 2011-01-19 13:54:30.000000000 +0100 *************** *** 21,26 **** --- 21,27 ---- #define PL2303_PRODUCT_ID_MMX 0x0612 #define PL2303_PRODUCT_ID_GPRS 0x0609 #define PL2303_PRODUCT_ID_HCR331 0x331a + #define PL2303_PRODUCT_ID_MOTOROLA 0x0307 #define ATEN_VENDOR_ID 0x0557 #define ATEN_VENDOR_ID2 0x0547 *** drivers/usb/serial/pl2303.c.orig 2011-01-21 09:11:09.000000000 +0100 --- drivers/usb/serial/pl2303.c 2011-01-19 13:58:22.000000000 +0100 *************** *** 50,55 **** --- 50,56 ---- { USB_DEVICE(PL2303_VENDOR_ID, PL2303_PRODUCT_ID_MMX) }, { USB_DEVICE(PL2303_VENDOR_ID, PL2303_PRODUCT_ID_GPRS) }, { USB_DEVICE(PL2303_VENDOR_ID, PL2303_PRODUCT_ID_HCR331) }, + { USB_DEVICE(PL2303_VENDOR_ID, PL2303_PRODUCT_ID_MOTOROLA) }, { USB_DEVICE(IODATA_VENDOR_ID, IODATA_PRODUCT_ID) }, { USB_DEVICE(IODATA_VENDOR_ID, IODATA_PRODUCT_ID_RSAQ5) }, { USB_DEVICE(ATEN_VENDOR_ID, ATEN_PRODUCT_ID) }, Remove the old module (rmmod pl2303) and insert the new one (insmod <yoursrckernelroot>/drivers/usbserial/pl2303). Check that the usbserial module is running (modprobe usbserial). If the insmod command fails, it depends on the wrong values put in the Makefile. Check "vermagic" using modinfo against old and new modules. Hope this helps. Dario.
