A router nem tudja elvenni az USB tápját?

Van egy picike TP-Link TL-WR842N v3 router-em. Dugtam bele egy USB hubot, abbe egy pendrive-ot. Ma elakadt a file-ok másolása. A pendrive magába fordult, eltűnt a /dev/sda. Próbálkoztam távolról az

rmmod ehci_platform

és

modprobe ehci_platform

parancsokkal. Aztán kénytelen voltam fizikai közelségben kihúzni és visszadugni a pendrive-ot. Ez lett belőle:

Van ott egy attempt power cycle üzenet, amelyből arra következtetek, a kernel kikapcsolná az USB portot, csak ezek szerint ezt a hardware nem tudja, hiszen a pendrive fizikai eltávolítása és visszadugása oldotta meg a problémát. Kár. :(
