我有一个旧的Nike + Sportband(image here)。耐克决定取消对该产品的支持。我想提取数据然后解码它。有人在C中编写了一个有效的代码(link download)。我想用Python做,所以我决定使用 PyUSB 。
代码:
import sys
import usb.core
import usb.util
VENDOR_ID = 0x11ac
PRODUCT_ID = 0x4269
device = usb.core.find(idVendor=VENDOR_ID, idProduct=PRODUCT_ID)
print device
if device is None:
sys.exit("Device not found.")
if device.is_kernel_driver_active(0):
try:
device.detach_kernel_driver(0)
print('Kernel driver detatched.\n')
except usb.core.USBError as e:
sys.exit("Could not detatch kernel driver: %s" % str(e))
try:
device.set_configuration()
#device.reset()
print('Configuration Ok')
except usb.core.USBError as e:
sys.exit("Could not set configuration: %s" % str(e))
# read a data packet
data = device.read(0x81,8,10000)
print data
我总是收到这个错误:
usb.core.USBError: [Errno 110] Operation timed out
有什么建议吗?
