usb error -32

Thu Jul 04, 2013 1:01 pm

Hello

I try to plug an oregonscientific LW301 weather station on the rpi.

I tried to plug it directly and thru a usb powered hub, and I got the following message :

usb errors continue for pages to pages.

I read on internet that this error can be related to lack of usb power. But as you see, sda is a usb powered disk plugged in the usb hub and it works well.

Do you have any clue to resolve this ?

Thx

Greg.

What model of RPi? What's the rated output of your power supply? Have you got a decent cable between the power supply and your RPi?

I assume you did not notice that the top post is almost 3 years old... ;)
