RPI 2 CD-ROM Unmounts and Remounts on its own - Raspberry Pi Forums

-

hello,
i've got raspberry pi 2 , i'm trying mount cd-rom it. i've found there plenty of posts can me out, i've run seems unique problem. i'm running jessie lite on pi, , i'm tunneled in via ssh laptop. when plug usb cd drive, makes repetitive sound it's attempting read cd, fails. continuously happens until unplug it. found if go [i /dev[/i] , type in ls, there's 50/50 chance of cdrom , sr0 showing up. if repeatedly type ls in dev, cdrom , sr0 may or may not show each time.

i've plugged cd player laptop, , works fine. both cd player , disc that's in work on fedora 22. i've plugged cd player raspberry pi 2 volumio flashed on it, , same thing happened raspberry pi jessie lite. i've tried plugging cd player wall, , seems attempt read it, stops. doesn't repeat cycle. i've tried cd player, , same thing seems happen 1 well.

has had problem before, or there may know issue may be?

have increased available usb current default of 600ma (shared on 4 usb ports) 1200ma adding max_usb_current=1 config.txt? (cdrom drives, usb hdd's, can power hungry). else have plugged usb ports?
trev.

arduino bug sur secteur, batterie, mais pas en usb?

bonjour, je travaille sur un premier projet de barrière infrarouge pour photographier les oiseaux, https://www.youtube.com/watch?v=8xzqd9iefgy&feature=youtu.be quand je suis alimenter en usb tout va bien, mais lorsque je passe par une alimentation extérieur (9v 12v secteur 12v) plus rien ne marche, la led clignote, les relais basculent n'importe comment. il me semble que se sont les capteurs qui bugs...(pas assez de courant?) 2 capteur ir = 2x100ma 2 relais = 2x40ma 1 diode, 1 push buttom la carte elle même... on est environ à 400ma. je ne comprends pas pourquoi ça coince!   le régulateur de la carte est prévu pour alimenter la carte et quelques petits accessoires pas trop gourments en courant. si on lui en demande trop il chauffe et la tension délivrée s'effondre. l'usb est, elle, prévue pour délivrer jusqu'à 500 ma. avec tous les ma consommés il faut une alim 5v supplémentaire. alim 5v +/- 5%, avec le 0v relié à celui de la carte...
