here, if you are using ubantu, i should tell you that , you should disable CONFIG_USB_SUSPEND which can be done by having a reload of the module "usbcore" with the option "autosuspend=-1.".unloading the usbcore once the system is booted is a very tricky and hard process to carry with.

re: unable to connect USB and 'device descriptor read/64', error in ubuntu

it's a really tough job to hard test USB stuff in a virtual machine and there are instructions to disable CONFIG_USB_SUSPEND without reloading usbcore. here you should make a try for this.

it usually comes with usbcore (CONFIG_USB) compiled as a module and CONFIG_USB_SUSPEND
enabled (at least on Ubuntu).

you should follow the below mentioned techniques to disable autosuspend
try to recompile kernel with no CONFIG_USB_SUSPEND

make a configuration of /etc/modprobe.d/ with a file containing
"options usbcore autosuspend=-1"
depending on your kernel you can make a setting to 0

If your system requires the modprobe configuration file above, and if your
system makes use of initrd (probably does) then you will require to rebuild the
initrd for your kernel .this will have some effect on it.

in my case, i made an attempt with the modprobe thing with the help of camera and there was some solution to it. i think this would be the problem and it will be sorted out.

according to me the possible solution to this could be by trying with the terminal type: echo -1 >/sys/module/usbcore/parameters/autosuspend and afterward log in as root . simply reboot after this.

i think , you should check the total output of 'dmesg | tail' after you plug in the device. and in short as root:
echo Y > /sys/module/usbcore/parameters/old_scheme_first . i think this will work in your case.
