apcupsd - periodicke odpojovani usb ups

[Josef Hrabec]

Hezky den,

mam pripojenou UPS APC Back-UPS 500 k serveru NEC Express5800/120Rf-1
prostrednictvim USB kabelu s instalovanym FreeBSD RELEASE 7.3 a
apcupsd-3.14.8_1. V okamziku, kdy nastartuji apcupsd daemon, tak se zacne
zminena UPS periodicky odpojovat a zase pripojovat. Apcupsd pak hlasi
periodicky ztratu a opetovne obnoveni spojeni s UPS. Pokud se apcupsd
zastavi, tak UPS zustava pripojena a dale se jiz tento jev neopakuje. V
logu to pri spustenem apcupsd vypada takto:

Zkusil jsem rekompilovat kernel bez podpory uhid a nasledne take bez ukbd,
ums a udbp, problem vsak stale pretrvava. Pokusil jsem se take tuto UPS
pripojit k obdobnemu serveru NEC Express5800/120Rd-1 s instalovanou
shodnou verzi FreBSD a Apcupsd, ale problem vsak pretrvava i tam.

Drive byla tato UPS pripojena k obycejnemu PC s FreeBSD RELEASE 6.4 a
apcupsd-3.14.5_1 a tam to bezelo bez problemu.


Pokud jste se nekdo nahodou setkal s obdobnym problemem s periodickym
odpojovani UPS s USB rozhranim a podarilo se jej nejak vyresit, rad bych
poprosil o pripadne postrehy.

Diky,
Pepa.
