It takes not more than 10 minutes to open the hard disk.
Well you don't have high expectations if you think 10minutes to open a disk is not a long time
Of course you can get some functionality from USB 1 but it is so slow (1.5 MB/s or 12 Mbit/s) that it's a lost case mostly
Many applications would time out before data is downloaded from that disk + that you seem to use FAT which is a disaster on a disk that large even if you partition it a lot - you should not really have more than 32 GB in a partition with FAT32
This is a lost case - sad perhaps but true
With the disk connected run lsusb (l is a lower case L) and post here
It might be detected.....
