[j-nsp] USB detection in RE-A-2000

[Alain Briant]

Hi dong bei


I don't have this kind of card here with me but when I want to check the 
insertion removal of an external storage device I first do
a "monitor start messages"

for example after the insertion of a compact-Flash on an M7i you have this:

Jan 17 10:30:03.240 2008  BFD_CNCE_Alain_Sam /kernel: pccard: card 
inserted, slot 0
Jan 17 10:30:06.716 2008  BFD_CNCE_Alain_Sam chassisd[3031]:

Jan 17 10:30:08.986 2008  BFD_CNCE_Alain_Sam pccardd[2929]: Card

Jan 17 10:30:21.440 2008  BFD_CNCE_Alain_Sam /kernel: ad3s2: cannot find 
label (no disk label)

after the insertion of a usb KEY on a J serie you have this:

Jan 17 10:58:05  CE1_J6300 /kernel: umass0: SanDisk Corporation Cruzer 
Micro, rev 2.00/0.10, addr 2
Jan 17 10:58:05  CE1_J6300 chassisd[2898]: CHASSISD_SNMP_TRAP7: SNMP 
trap generated: FRU insertion (jnxFruContentsIndex 9, jnxFruL1Index 1, 
jnxFruL2Index 1, jnxFruL3Index 0, jnxFruName USB Hub, jnxFruType 6, 
jnxFruSlot 1)
Jan 17 10:58:05  CE1_J6300 /kernel: da0 at umass-sim0 bus 0 target 0 lun 0
Jan 17 10:58:05  CE1_J6300 /kernel: da0: <SanDisk Cruzer Micro 0.1>

Jan 17 10:58:05  CE1_J6300 /kernel: da0: 650KB/s transfers

sectors: 64H 32S/T 488C)



Finally you can type some show commands to see the recognized devices:
"show chassis hardware detail":

on M7i with Compact-Flash istalled

Routing Engine   REV 09   740-009459   1000606414        RE-5.0

  ad3     488 MB  SanDisk SDCFH-512    016615A1806O5936  PCCard


on M7i without Compact-Flash istalled

Routing Engine   REV 09   740-009459   1000606414        RE-5.0
  ad0     244 MB  256MB CHH            5073I8C25A4027001A Compact Flash

On the J serie with USB installed:

Routing Engine   REV 09   750-010006   BTRD50500566      RE-J.3
  ad0     244 MB  Hitachi XX.V.3.4.0.0 X0502 20041202221804 Compact Flash
  usb0 (addr 1)  UHCI root hub 0       Intel             uhub0
  usb0 (addr 2)  Cruzer Micro 20817    SanDisk Corporation umass0


On the J serie without USB installed:

Routing Engine   REV 09   750-010006   BTRD50500566      RE-J.3
  ad0     244 MB  Hitachi XX.V.3.4.0.0 X0502 20041202221804 Compact Flash



At least be careful of the brand of USB you use

I understand that the USB should come delivered with the router (so this 
shouldn't be an issue)

Let me know if this helps you

regards
Alain
