Are you sure that it is not broken? Did you try it with other distributions (live CDs) or Windows?

Tried it today on Windows XP. Works perfectly. File structure shown in Windows Explorer.

So how did this happen, updated kernel or libusb? Did you try to google or report upstream? It's not an issue we can fix

My last update was on 27-April. Connection worked. I went on holidays and came back on 14-May, did an update including gnome-shell and it was broken. Funny is that it works perfectly on Windows XP including correct display of capacity.

Works after today's kernel26 update and can be closed
