Hello I have two completely different UPS that turn out to use the same driver. Both work with blazer_usb my LSUSB says: Bus 001 Device 005: ID 0665:5161 Cypress Semiconductor USB to Serial Bus 001 Device 004: ID 0665:5161 Cypress Semiconductor USB to Serial my lsusb -vd 0665: says: pi at elektra:~ $ lsusb -vd 0665: Bus 001 Device 005: ID 0665:5161 Cypress Semiconductor USB to Serial Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 1.10 bDeviceClass 0 (Defined at Interface level) bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 8 idVendor 0x0665 Cypress Semiconductor idProduct 0x5161 USB to Serial bcdDevice 0.02 iManufacturer 1 Cypress Semiconductor iProduct 2 USB to Serial iSerial 0 bNumConfigurations 1 Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 34 bNumInterfaces 1 bConfigurationValue 1 iConfiguration 3 (error) bmAttributes 0x80 (Bus Powered) MaxPower 100mA Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 bNumEndpoints 1 bInterfaceClass 3 Human Interface Device bInterfaceSubClass 0 No Subclass bInterfaceProtocol 0 None iInterface 4 Sample HID HID Device Descriptor: bLength 9 bDescriptorType 33 bcdHID 1.00 bCountryCode 0 Not supported bNumDescriptors 1 bDescriptorType 34 Report wDescriptorLength 27 Report Descriptors: ** UNAVAILABLE ** Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x81 EP 1 IN bmAttributes 3 Transfer Type Interrupt Synch Type None Usage Type Data wMaxPacketSize 0x0008 1x 8 bytes bInterval 32 Device Status: 0x0000 (Bus Powered) Bus 001 Device 004: ID 0665:5161 Cypress Semiconductor USB to Serial Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 1.10 bDeviceClass 0 (Defined at Interface level) bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 8 idVendor 0x0665 Cypress Semiconductor idProduct 0x5161 USB to Serial bcdDevice 0.02 iManufacturer 1 INNO TECH iProduct 2 USB to Serial iSerial 0 bNumConfigurations 1 Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 34 bNumInterfaces 1 bConfigurationValue 1 iConfiguration 3 20100813 bmAttributes 0x80 (Bus Powered) MaxPower 100mA Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 bNumEndpoints 1 bInterfaceClass 3 Human Interface Device bInterfaceSubClass 0 No Subclass bInterfaceProtocol 0 None iInterface 4 Sample HID HID Device Descriptor: bLength 9 bDescriptorType 33 bcdHID 1.00 bCountryCode 0 Not supported bNumDescriptors 1 bDescriptorType 34 Report wDescriptorLength 27 Report Descriptors: ** UNAVAILABLE ** Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x81 EP 1 IN bmAttributes 3 Transfer Type Interrupt Synch Type None Usage Type Data wMaxPacketSize 0x0008 1x 8 bytes bInterval 1 Device Status: 0x0000 (Bus Powered) pi at elektra:~ $ As you can see, the only difference is iManufacturer 1 INNO TECH Is there any way I could use that value to differentiate between them? I cannot change bus, this is on a raspberry pi Thanks! -E -------------- next part -------------- An HTML attachment was scrubbed...
