如何查询/proc/bus/usb/devices中的U盘信息

本帖最后由 cutecactus 于 2011-06-13 12:28 编辑

如/proc/bus/usb/devices的内容如下：
T:  Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#=  1 Spd=12  MxCh= 2
B:  Alloc= 11/900 us ( 1%), #Int=  1, #Iso=  0
D:  Ver= 1.10 Cls=09(hub  ) Sub=00 Prot=00 MxPS= 8 #Cfgs=  1
P:  Vendor=0000 ProdID=0000 Rev= 2.06
S:  Manufacturer=Linux 2.6.11-1.1369_FC4 uhci_hcd
S:  Product=UHCI Host Controller
S:  SerialNumber=0000:00:07.2
C:* #Ifs= 1 Cfg#= 1 Atr=c0 MxPwr=  0mA
I:  If#= 0 Alt= 0 #EPs= 1 Cls=09(hub  ) Sub=00 Prot=00 Driver=hub
E:  Ad=81(I) Atr=03(Int.) MxPS=   2 Ivl=255ms

T:  Bus=01 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#=  3 Spd=12  MxCh= 7
D:  Ver= 1.10 Cls=09(hub  ) Sub=00 Prot=00 MxPS= 8 #Cfgs=  1
P:  Vendor=0e0f ProdID=0002 Rev= 1.00
S:  Product=VMware Virtual USB Hub
C:* #Ifs= 1 Cfg#= 1 Atr=e0 MxPwr=  0mA
I:  If#= 0 Alt= 0 #EPs= 1 Cls=09(hub  ) Sub=00 Prot=00 Driver=usb-storage
E:  Ad=81(I) Atr=03(Int.) MxPS=   1 Ivl=255ms

T:  Bus=01 Lev=02 Prnt=01 Port=01 Cnt=01 Dev#=  3 Spd=12  MxCh= 8
D:  Ver= 1.10 Cls=09(hub  ) Sub=00 Prot=00 MxPS= 8 #Cfgs=  1
P:  Vendor=0e0f ProdID=0002 Rev= 1.00
S:  Product=VMware Virtual USB Hub
C:* #Ifs= 1 Cfg#= 1 Atr=e0 MxPwr=  0mA
I:  If#= 0 Alt= 0 #EPs= 1 Cls=09(hub  ) Sub=00 Prot=00 Driver=hub
E:  Ad=81(I) Atr=03(Int.) MxPS=   1 Ivl=255ms

我如何得到如下内容呢？Shell语句怎么个写法？谢谢。
T:  Bus=01 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#=  3 Spd=12  MxCh= 7
D:  Ver= 1.10 Cls=09(hub  ) Sub=00 Prot=00 MxPS= 8 #Cfgs=  1
P:  Vendor=0e0f ProdID=0002 Rev= 1.00
S:  Product=VMware Virtual USB Hub
C:* #Ifs= 1 Cfg#= 1 Atr=e0 MxPwr=  0mA
I:  If#= 0 Alt= 0 #EPs= 1 Cls=09(hub  ) Sub=00 Prot=00 Driver=usb-storage
E:  Ad=81(I) Atr=03(Int.) MxPS=   1 Ivl=255ms

找到了，这样写就OK了。

awk 'BEGIN{FS=""; RS=""}{if($0~/usb-storage/) print $0}' /proc/bus/usb/devices
