My ChipWhisperer-Lite stoped working so I tried to reset its firmware by shorting JP2 while the Lite was on. After shorting the pins, I unplugged and replugged the USB connector and now ,I can see D2 and D9 diodes lit dimly everytime I connect it to my PC.
However the USB is not recognized anymore. When I use the next commands:
import chipwhisperer as cw
scope = cw.scope()
I get the error:
OSError Traceback (most recent call last)
1 import chipwhisperer as cw
----> 2 scope = cw.scope()
c:\users\asizu\chipwh~1\git\home\portable\chipwhisperer\software\chipwhisperer_init_.py in scope(scope_type, sn)
226 from chipwhisperer.common.utils.util import get_cw_type
227 if scope_type is None:
–> 228 scope_type = get_cw_type(sn)
229 scope = scope_type()
c:\users\asizu\chipwh~1\git\home\portable\chipwhisperer\software\chipwhisperer\common\utils\util.py in get_cw_type(sn)
501 name = “”
502 if len(possible_sn) == 0:
–> 503 raise OSError(“USB Device not found. Did you connect it first?”)
505 if (len(possible_sn) > 1):
OSError: USB Device not found. Did you connect it first?
How can I solve this? I tried to uninstall from the device manager and the right drivers for windows are installed also. I have no clue of what is happening.
