Answer : A yellow USB port usually denotes an "always on" port. It supplies power to the device plugged into it even when the laptop is off. If it's a Lenovo ThinkPad chances are it's the "always on USB", which is a special port that remains powered when the computer is asleep, or when the computer is fully powered off and the AC adapter plugged. This allows you to, for example, keep charging your phone or wireless gamepad without having to keep your computer running. http://www.asprangers.com/post/2012/10/02/What%E2%80%99s-in-color-Yellow-Blue-Gray-color-USB-Ports-on-Lenovo.aspx It can be whatever colour that your manufacturer wants it to be - I do not think there is a standard. That being said, every product I have seen that supports USB 3 seems to have a blue socket, so there may be one! If it is yellow, my guess is that it may be a way to indicate enhanced/increased/special power output. What model do you have? If you write the model number,...

Answer : You could resolve the error by repeating the steps : Run the installer. Open a shell ( ALT + F2 ). Create the directory cdrom directly on the root of the file system: mkdir /cdrom Note : If you got problems making the directory /cdrom, disable the CD-rom player in BIOS or disconnect the cable Mount the USB as if it is a CD-ROM: mount -t vfat /dev/sdb1 /cdrom Where sdb1 is your USB device. You could carry on installation now After executing mount -t vfat /dev/sdb1 /cdrom , cd into the /cdrom directory and do an ls to see if the files are there. Then press ALT - F1 to go back, continue and re-select "detect CDROM" Source :ubuntu and debian Another layman solution was : when the Window shows CDROM couldn't be mounted , Unplug your USB from system and re insert it wait for mount/ detection (usb LED glow) Hit Continue You could do what I did. Hit escape, type install, hit enter, skip CD drive. If you ...

Answer : Yes. This is definitely possible, requiring no modifications or drivers on the PC. As the OP mentions, the USB identification on the phone end is ultimately done in software (in this file https://github.com/android/kernel_msm/blob/android-msm-2.6.35/drivers/usb/gadget/composite.c), and it could be modified to identify itself as a standard USB keyboard. This change would require a couple of things. A modified kernel with a patched USB driver An Android app that could talk to some interface exposed by the modified USB driver. There was a paper published a couple of years ago (titled Exploiting smart-phone USB connectivity for fun and profit ) that described using a phone to brute-force desktop login screens. The method they used involved making the phone appear as a USB keyboard. This doesn't exactly answer your question, but it might help in your use case. Maybe you want to have a look at InputStick. It'll be a USB thumb drive that you pair to Android via...
