I have just received notification from IREX that my dr1000 is repaired and is send to me, hope I will have it back at monday
. After all I think that IREX was very correct in the handling of the issue. For those who have problems in charging the dr1000 to 100% full capacity, I recommend opening a ticket, in my case the motherboard had to be replaced (but test before some other usb ports of your computer for the charging as I think it is indeed possible that some wall usb chargers do not give the correct voltage).
