usb 2.0

[phuntastiko]

ciao,
ho uan chiave certamente 2.0 e una scheda madre asus a7v600-x con usb 2.0 ma la velocità di transfer è quella di una 1.1
c'è modo di abilitare la 2.0 su linux?o verificare le effettive velocità selle porte?
grazie

Deve essere caricato il driver ehci-hcd, è molto strano se non ti è stato caricato automaticamente. Attento che non sempre tutte le porte hardware sono usb 2.0, alcune possono essere 1.1

significa che sono usb 2.0?
perchè ci ho messo 10 minuti per spostare 1,5 gb?

Un pò bassina per un usb 2.0

Non sono sicuro, date le informazioni che hai inviato, che sia effettivamente connesso alle porte ehci.
Affinché il dispositivo vada in usb 2, devi ottenere qualcosa tipo:

usb 5-<id>: new high speed USB device using ehci_hcd and address <addr>

Dal tuo log, non vedo nulla sul bus 5 (quello di ehci_hcd).

[phuntastiko]

cosa posso fare?

[ilsensine]

Intando mandami il tuo dmesg completo con la chiavetta attaccata

[phuntastiko]

spero sia corretto, non so se intendevi questo:

Sembrerebbe tutto ok.
Cosa riporta hdparm -t /dev/sda?

[phuntastiko]

daniele@daniele:~$ hdparm -t /dev/sda

/dev/sda:
Timing buffered disk reads: 28 MB in 3.21 seconds = 8.73 MB/sec

daniele@daniele:~$

[ilsensine]

La velocità raw è di 70Mbit/sec, non credo che puoi pretendere molto di più da un dispositivo di quel tipo.
Però la velocità del file system è decisamente inferiore (1.5GB/10min = ~20Mbit/sec); cosa riporta cat /proc/self/mounts quando il dispositivo viene "montato"?

[phuntastiko]

cosa intendi quando viene montato?

Niente sync o simili...

Forse la differenza è dovuta al fatto che la scrittura su flash è di norma molto più lenta della lettura. Per averne la certezza occorrerebbe fare un test di scrittura sul device, bypassando il file system, ma sarebbe un procedimento distruttivo.

Puoi provare il trasferimento di un grosso file da windows e vedere quanto ci mette? (compreso l'eventuale tempo per "smontare" il dispositivo, se non trascurabile)

[phuntastiko]

ho win ma senza sp,quindi l'usb è sicuramente 1.1
a meno che a te non interessi questo parametro,ma dato che è quello di cui si discute...

[ilsensine]

No no, in usb 1.1 dovresti avere velocità addirittura più ridotte. Provare per credere, rimuovendo il driver ehci_hcd.

Credo che sia una limitazione nella velocità in scrittura della flash, comunque. Se rileggi il file da 1.5GB, dovresti osservare una velocità nettamente maggiore, se vuoi provare...

[phuntastiko]

intendi leggerlo dalla flash o spostarlo sull'hd?
come misuro la velocità?
grazie di tutto

[ilsensine]

Con un bel
time cat /media/KINGSTON/Grosso_file.avi > /dev/null

[phuntastiko]

il risultato:

daniele@daniele:~$ time cat /media/KINGSTON/a.avi > /dev/null
real    1m38.223s
user    0m0.036s
sys     0m2.228s

l'avi è di 787 MB. serve altro?

[ilsensine]

Originariamente inviato da phuntastiko

il risultato:

daniele@daniele:~$ time cat /media/KINGSTON/a.avi > /dev/null
real    1m38.223s
user    0m0.036s
sys     0m2.228s

l'avi è di 787 MB. serve altro?

...quindi leggi a 64Mbit/sec, quasi la velocità raw.

Quindi non è un problema di connessione usb, ma di lentezza di scrittura della flash della tua penna.

[phuntastiko]

uff,e dire che l'ho comprata ieri apposta perchè era usb2.immagino che non si possa fare altro,vero?
grazie di tutto lo sbattimento
