Hello Guy's

last weekend i had the idea to try some war-cycling. and for that i grabbed my mk5 from the shelf and startet scurging the interwebs for information on how to connect a USB GPS dongle to the mk5. this was actualy real easey to do. and i installed the following for testing: Kismet_server and read some where that kismet could directly connect to my USB device. turns out that this is not the case for me. so i installde GPSD and after that kismet found a damn good GPS lock. i decided to run some more tests before i would go on my trip. and found that after starting and stopping Kismet & GPSD a few times the ttyUSB0 dissapears from my /dev folder.

now my question is am i the only one having ttyUSB0 disapear on me or are there others on the forum with the same problem.

and if so did any one find the reason why or solved it?

when i noticed these problems my setup was as follows.

1. pinapple mk5 connected with mains adapter to power.

USB GPS dongle directly connected to the pineapple

2. Laptop connected over ethernet to the pineapple for ssh purpose.

the only thing i can think of from your remark is that the dongle asks to much power from the pineapple.

i'll take a look at the specs of the dongle to be sure.

but it worked fine on a raspberry last time.

FYI the dongle is a G.mouse BU-353 USB dongle

found the specs:

GPS Chipset SiRF STAR IV GSD4e

is 60mA realy to much for a pineapple?
