This needs to be solved. Not only delays USB communication as an infinite loop is generating huge logs which basically screw up my system.

This shows up in other distros as well with other kernel versions: Example: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/256767
By the way, if the port 6 in the error message refers to bus then I have no bus 6. lsusb reports: $ sudo lsusb Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 002: ID 045e:0039 Microsoft Corp.

Just found out that disconnecting my sd/mmc drive from the motherboard will stop this from happening. It is not a hardware problem as I have tried to connect the same drive to other pins (which I know are working fine) and the exact same happens. It seems to be related to how the kernel detects the drive... is this possible? Searching this error on google, it doesn't seem to be too uncommon!
Can you post the dmesg so I can see anything that is written before the looping lines. You can snip it once the "unable to enumerate " start to take over. And, last working kernel version?
This is a new gentoo install. There is no latest working kernel version. I disconnected the device so I am not getting the problem. I will try to reconnect it to post a complete dmesg.
