Default MD782 firmware question

I bought a used MD782 VHF radio and it has version 5.00.15.001 in it now. I have the upgrade file to bring it up to 7.00.11.010 and the next upgrade file to get it to current version but when I put the radio in upgrade mode and connect the cable my computer does not recognize the USB cable. I can read and write just fine with same cable and same port, but when the radio is in upgrade mode it will not connect so I tried my other computer and it does the same thing. I have done several firmware updates and had no issues with this same set up is there something different I have to do with firmware this old, I have never had a radio with this old version before.

V6.01.05.006

V7.00.11.007
V7.06.06.000 You MUST have firmware v7.0 to use v7.06

Here is a link to the DMR&PDT Subscriber Firmware Hytera Upgrade Guide R7.0 . If you don't have the guide with the firmware file. The guide will show how to properly update the firmware for the Hytera radio that you own. Hopefully this will be helpful.

OK thanks I have all that information and the upgrade files, please read what I wrote in the first place. The issue is not the upgrade files nor the process to upgrade, the issue is when I put the radio into firmware update mode and I connect my cable the computer or in my case computers as in more than one will no longer recognize the USB being connected. You power off the radio and power it right back on in normal operating mode the same computers now will work fine and read and write normally. Now power off the radio connect the ground and PTT and power it on in the firmware mode and reconnect the cable and it again give you the error the USB device is not recognized.
