Public bug reported: More specifically the code which creates USB root hubs within the computer itself.
There are a number of devices based on the ATtiny45 or 85 which have a USB stack and recommend a set of standard resistors to identify the device as far as hardware. Under Windows and MacOSX, these are properly recognized as a keyboard (or mouse, joystick, etc). One example is http://www.sparkfun.com/commerce/product_info.php?products_id=9147 - code and schematics are FLOSS. It reads it's A/D and "types" into whatever is opened. Under Linux it is NOT recognized unless plugged into the hub, but is recognized when plugged into any external hub. lsusb returns nothing. dmesg returns: [222156.412137] usb 2-2: new low speed USB device using uhci_hcd and address 24 [222156.536130] usb 2-2: device descriptor read/64, error -71 [222156.764115] usb 2-2: device descriptor read/64, error -71 [222156.980961] usb 2-2: new low speed USB device using uhci_hcd and address 25 [222157.116080] usb 2-2: ep0 maxpacket = 16 [222157.228059] usb 2-2: new low speed USB device using uhci_hcd and address 26 [222157.643905] usb 2-2: device not accepting address 26, error -71 [222157.752227] usb 2-2: new low speed USB device using uhci_hcd and address 27 [222158.168138] usb 2-2: device not accepting address 27, error -84 [222158.168186] hub 2-0:1.0: unable to enumerate USB device on port 2 [222168.480082] usb 2-2: new low speed USB device using uhci_hcd and address 28 [222168.600062] usb 2-2: device descriptor read/64, error -71 [222168.768185] hub 2-0:1.0: unable to enumerate USB device on port 2 [222169.485159] usb 2-2: new low speed USB device using uhci_hcd and address 29 [222169.608150] usb 2-2: device descriptor read/64, error -75 [222170.244121] usb 2-2: device not accepting address 29, error -71 [222170.352259] usb 2-2: new low speed USB device using uhci_hcd and address 30 Linux tz-hpmini 2.6.28-15-generic #49-Ubuntu SMP Tue Aug 18 18:40:08 UTC 2009 i686 GNU/Linux I have more than one of these, and I would be willing to send one to someone with the expertise to fix the problem, but they aren't very expensive and the documentation for the hardware and software is online. ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- AVR Stick and other ATtinyx5 USB devices aren't recognized https://bugs.launchpad.net/bugs/422159 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
