boa noite pessoal!

alguém tem sofrido com problemas de montagens de dispositivos USB, leia-se modens 3G?

acontece que recentemente tenho acompanhado as mensagens em /var/log/messages e está tipicamente assim quando conecto meu modem 3G:

Simplesmente o usb-modeswitch não consegue liberar o dispositivo para uso e isso fica num loop infinito, cheguei ao cúmulo de removê-lo e passar a ejetar o dispositivo com o eject para conseguir utilizar essa maravilha de serviço chamado net 3G:

$ sudo eject /dev/sr1

Pesquisando na internet parece que isso é coisa do kernel 3.1 e que só se resolverá com um patch para a versão 3.1.5:

Vou aproveitar esse tópico "só seu" (rsrsr) para perguntar: - vale a pena atualizar o Kernel do Deian Squeeze?

Pergunto porque o Kernel original, o 2.6.32, está rodando muito bem, mas talvez a atualização pelo backports melhore ainda mais o desempenho do Squeeze.

foi parcialmente resolvido, mas começo a achar que não é especificamente por causa do kernel porque mesmo instanado o CrunchBang que usa o kernel 2.6.39 ocntinuei tendo problemas, que só resolvi removendo:

modemmanager, mobileprovideralgumacoisa e usb-modeswitch

daí instalei o porco discador da Vivo, resolvi a pendenga que ocorria com ele que ao ser instalado quebrava o APT e por enquanto está funcionando e sem queda na conexão como ocorre no Windows.

comecei a fazer uma dica lá pro meu blog sobre o uso do mesmo mas ainda não terminei.

sobre atualizar o kernel eu não deveria ter instalado o CrunchBang e sim um Debian puro, já que o CrunchBang usa bastante pacotes do Backports, assim usando o Squeeze com seu kernel eu saberia se teria algum problema ou não.

thanks por não me deixar sozinho! rsrsrs

de volta ao passado!

nada de modemmanager, usb-modeswitch, mobile-broadband-provider-info e network-manager (esse eu não usava mesmo!).

simplesmente colei uma conf de regras para o UDEV que eu usava antigamente e que estavam num CD de backup:

# é a mesma conf que vem no aplicativo da Vivo.
#
# udev rules file for supported cameras

Voltando... o modem é montado, aberto no gerenciador de arquivos como CD-ROM, demontado automaticamente e em seguida liberado para uso, seja através de qualquer app: wvdial, ppp, network-manager e por aí vai!

* testado no Debian Squeeze (CrunchBang) com os kernels 2.6.39-2 do Debian Backports e o kernel 2.6.32-5 do próprio Squeeze.


** agora farei os mesmos testes no Arch Linux apenas removendo as apps (modemmanager, usb-modeswitch, mobile-broadband-provider-info e network-manager), adicionando a regra e verificando se com o kernel 3.1.x funciona da mesma forma que no Debian.


*** é nessas hora que fico feliz por usar Linux, não pelos problemas em si, mas pela possibilidade de aprendizado, veja que uma coisa que eu utilizava na época do kernel 2.6.26 do Debian Lenny me salvou hoje que usava o kernel da série 3.1.x. Não só isso, como pelas inúmeras fontes de pesquisa disponíveis, sejam artigos, Wikis, posts de foruns e etc.

quando não houver desafios o melhor é voltar ao Windows e conviver com os vírus e trojans praquele SO.

no Arch tenho que usar o eject:

e depois:

ou
$ sudo wvdial 3g

como dito lá em cima que isso era um problema que só seria resolvido com o kernel 3.1.5.x, resolvi instalar no Arch Linux o Kernel-CK 3.1.5-2:

$ sudo pacman -S linux-ck-kx linux-ck-kx-headers


Em seguida instalei as apps que eu havia removido:

$ sudo pacman -S modemmanager usb_modeswitch mobile-broadband-provider-info


E bastou editar o arquivo /etc/usb_modeswitch.setup, removendo as partes desnecessárias e deixando-o assim:

Aproveitando que instalei um kernel otimizado para a arquitetura do processador:

ck-kx ==> AMD K7 (Athlon/Athlon XP)/K8 (Athlon 64, Athlon 64 X2, 23xx Quad-Core Barcelona, Sempron, Sempron 64)/K10-family (Athlon X2 7x50, Phenom X3/X4, Phenom II, Athlon II X2/X3/X4, Sempron 64 (Socket AM3 only), 61xx Eight-Core Magny-Cours) specific optimizations. Enables use of some extended instructions, and passes appropriate optimization flags to GCC.

Adicionei a opção elevator=bfq na linha do kernel do arquivo /etc/default/grub:

GRUB_CMDLINE_LINUX_DEFAULT="quiet elevator=bfq vga=791"

E ao final rodei para gerar um novo grub.cfg:

$ sudo grub-mkconfig -o /boot/grub/grub.cfg
