Pripoj telefon, pockej a otestuj jestli v momente, kdy se to zastavi pomuze:

rmmod usb_storage
modprobe usb_storage

Jsou kolem toho nejake bugy.. dej vedet.

Joo, tak to funguje :). Diky moc.
Kdyz rikas, ze jsou kolem toho nejake bugy, tak predpokladam, ze se to resi a neni treba to uz nikde hlasit, ze.
Btw, problem je vlastne v systemu nebo v telefonu? Jine telefony mi jdou pripojit v pohode.

Problem je s detekci toho CD a komponentou systemu ktera se jmenuje udisk. Bug 721966 713877 725978. Jako permamentni reseni je workaround:

# cat          /sys/module/block/parameters/events_dfl_poll_msecs
0
# echo 2000 >  /sys/module/block/parameters/events_dfl_poll_msecs

pripadne update systemd, udisk -> udisk2 ..
