Distro: Ubuntu 8.04.1 Problem: an unbranded USB-serial converter is not detected Steps taken to resolve the problem: (unsuccessful) force usb-serial detection by adding (Debian?) udev rules - detects device but incorrectly defaults to generic which doesn't work (successful) added vendor:product to pl2303 / recompile / insert module Further info: Windows drivers report "Cyber Logic" & "EPT Micro" as brands. lsusb dump: Bus 003 Device 002: ID 5372:2303 Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 1.10 bDeviceClass 0 (Defined at Interface level) bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 64 idVendor 0x5372 idProduct 0x2303 bcdDevice 3.00 iManufacturer 1 Superial Technology Inc. iProduct 2 USB-Serial Controller iSerial 0 bNumConfigurations 1 Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 39 bNumInterfaces 1 bConfigurationValue 1 iConfiguration 0 bmAttributes 0x80 (Bus Powered) MaxPower 100mA Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 bNumEndpoints 3 bInterfaceClass 255 Vendor Specific Class bInterfaceSubClass 0 bInterfaceProtocol 0 iInterface 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x81 EP 1 IN bmAttributes 3 Transfer Type Interrupt Synch Type None Usage Type Data wMaxPacketSize 0x000a 1x 10 bytes bInterval 1 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x02 EP 2 OUT bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0040 1x 64 bytes bInterval 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x83 EP 3 IN bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0040 1x 64 bytes bInterval 0 Device Status: 0x0000 (Bus Powered)

I got the idea from: http://www.linuxquestions.org/questions/linux-hardware-18/obscure-usb-serial-adapter-368278/ This patch adds the "Superial" USB-Serial converter to pl2303 so that it is detected, by the correct driver. Adds the relevant vendor:product (5372:2303) to the device tables in pl2303.c & pl2303.h. The patch has been tested against 2.6.24-22-generic.
