[g0tcha]

Hi

 

I have a problem wih my usrp1 when connecting to  any pc, when I power on the system the led stays solid if I plug in a usb the led remains the same no change in state

 

When I connect to my debian system I get the following error

 

[  275.640109] usb 1-1.4: new full speed USB device using ehci_hcd and address 5

[  275.712118] usb 1-1.4: device descriptor read/64, error -32

[  277.376259] hub 1-1:1.0: unable to enumerate USB device on port 4

 

I was told by ettus support it maybe relating to my firmware corruption of eeprom,  but I confirmed that my eeprom is NOT corrupted anyone is welcome to confirm . The other thing they mentioned which can allow me to connect or make usb work is RESET the flash anyone have any idea how to do this ?

 

Just some tests we conducted

D- = 3.2xx V

D+ = drop power from 1.xxx down

 

Any help appreciated
