RE: Intel USB 3.0 eXtensible Host Controller driver for 7720 inspiron 17r special edition

Hi Pete,

Thank you for the information; appreciate it.

Try updating the chipset drivers from our Support Site. Here is the link -> choose the operating system -> expand Chipset, download and install all the options listed. Then choose the operating system as Windows 7, download and install Intel USB 3.0 eXtensible Host Controller Driver and see if it helps.

Unfortunately, once the original recovery partition is deleted, it cannot be obtained again. Seems like the formatted before you purchased it. 

If it still doesn't work, then it might be a hardware issue and we may have to replace parts.

Please share the findings; will take it further.

Thanks & Regards,
Appu S
