Hi, guys I have the same situation with USB flash drive in the DELL (SK-8135) keyboard at Ubuntu 16.04 LTS
dmesg: [ 2677.375539] usb 7-1.3: new full-speed USB device number 6 using xhci_hcd [ 2677.487556] usb 7-1.3: not running at top speed; connect to a high speed hub [ 2677.511560] usb 7-1.3: New USB device found, idVendor=0781, idProduct=5571 [ 2677.511567] usb 7-1.3: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 2677.511571] usb 7-1.3: Product: Cruzer Fit [ 2677.511575] usb 7-1.3: Manufacturer: SanDisk [ 2677.511578] usb 7-1.3: SerialNumber: 4C530012740827123152 [ 2677.512059] usb 7-1.3: rejected 1 configuration due to insufficient available bus power [ 2677.512067] usb 7-1.3: no configuration chosen from 1 choice [ 2704.060356] usb 7-1.3: USB disconnect, device number 6 uname -a: Linux xubuntu 4.4.0-21-generic #37-Ubuntu SMP Mon Apr 18 18:33:37 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/203473 Title: rejected 1 configuration due to insufficient available bus power Status in devicekit package in Ubuntu: Confirmed Status in linux package in Ubuntu: Incomplete Bug description: Binary package hint: hal I'm not sure wether this is the right package, but I hope somebody will point me to the right direction if it is not. When I connect my portable music player (a cmx stingray 888) to the USB port on the front panel of my pc, it works without any problem. When I connect it to my keyboard which has an USB hub included, nothing happens. So I looked into my syslog and found the following lines: Mar 18 09:24:11 weintraube kernel: [ 215.220320] usb 2-2.2: new full speed USB device using uhci_hcd and address 7 Mar 18 09:24:11 weintraube kernel: [ 215.322158] usb 2-2.2: not running at top speed; connect to a high speed hub Mar 18 09:24:11 weintraube kernel: [ 215.344246] usb 2-2.2: rejected 1 configuration due to insufficient available bus power Mar 18 09:24:11 weintraube kernel: [ 215.344252] usb 2-2.2: no configuration chosen from 1 choice I think there should be a notification in this case, because a user new to ubuntu would expect the device to do something but instead gets no visible action. The message could be something like "the usb connector where you attached your device does not have enough power, try connecting on another one" (of course not by word - my english is not that good).
