Hi, I'm facing a very nasty problem with the USB using Blip and telosb. I've a small testbed set up where few telosb report data to a telosb IPBaseStation connected by USB to a laptop running Ubuntu 10.
The ip-driver is running and the tun0 interface works perfectly until, for some reason, the USB disconnects!!! Happened many times already and always after a random period of time (few hours or few days). Has anybody of you had the same problem? Please, have a look to my dmesg: [ 62.583495] device tun0 entered promiscuous mode [181469.402683] hub 1-0:1.0: port 1 disabled by hub (EMI?), re-enabling... [181469.403667] usb 1-1: USB disconnect, address 2 [181469.406021] ftdi_sio ttyUSB0: FTDI USB Serial Device converter now disconnected from ttyUSB0 [181469.406654] ftdi_sio 1-1:1.0: device disconnected [181469.627963] usb 1-1: new full speed USB device using ohci_hcd and address 3 [181469.777676] usb 1-1: configuration #1 chosen from 1 choice [181469.783296] ftdi_sio 1-1:1.0: FTDI USB Serial Device converter detected [181469.784171] usb 1-1: Detected FT232BM [181469.785634] usb 1-1: FTDI USB Serial Device converter now attached to ttyUSB1 As you can see the USB went off after more than 2 days of activity! I suspect it's related to the USB hardware rather than applications but, so far, it happens to me only using telosb. I google it a bit but I have not found solution yet Any comment is more than welcome Many thanks Davide _______________________________________________ Tinyos-help mailing list [email protected] https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
