USB device not recognized U30 Hoboware

We have been recording the weather parameters using U30 from last month. We already download the data three times and it was okay. However, this month when we try to download the data using USB connection, the laptop gave us the comment: "USB device not recognized: The last USB device you connected to this computer malfunctioned, and Windows does not recognize it". The status in hoboware window also didn't detect the device. Please help to solve this problem. Thank you
