I have a system using a variable number of Cypress FX2 devices to control data acquisition. The host system can be either windows 7 or 8. Each FX2 has three open pipes when in use. When I connect to a USB 2.0 host port I can connect a large number of units in various combinations of hubs and devices without any problem.
When I connect to a USB3 host port I get an "out of resource" message from the win 8 system or a "code 10 error" with win 7 when I connect in excess of 13 units (29 pipes) in any combination of hubs and units. All hubs and units are self powered.
Any help with this would be appreciated.
Show LessProcedure for running the WICED Sense TAG on USB Power:
- Remove the USB cable after you have successfully programmed the Tag
- Leaving the Battery cover off in this process, press the battery into the battery socket until you see the RED Led turn on
3. While holding the battery with your fingers making the battery connection, insert the USB Cable in the Tag
4. Release your finger from the battery, letting the battery drop out of the socket and you are now running the Tag from the USB Power

Introduction to Format of WICED Sensor Data
The following STMicro Sensors are used:
Please refer to the STMicro Web site for details on Sensor Data Sheets.
The iOS App receives notifications in this format:
struct
{
/// Bit mask of sensor data
/// Bit 0: When set, accelerometer included X (2 signed bytes), Y (2 signed bytes) and Z (2 signed bytes).
/// Bit 1: When set, gyro included X (2 signed bytes), Y (2 signed bytes) and Z (2 signed bytes).
/// Bit 2: When set, humidity included (2 unsigned bytes in percentage).
/// Bit 3: When set, magnetometer included X (2 signed bytes), Y (2 signed bytes) and Z (2 signed bytes).
/// Bit 4: When set, pressure included (2 bytes, pressure in mBar * 10)
/// Bit 5: When set, temperature included (2 unsigned bytes, temperature in C * 10).
UINT8 included_sensor_data;
/// sensor data.
/// Data included in the order of the bits set.
/// Max length is 20 bytes, may be smaller when data for only some sensors is included
/// in the notification.
/// Notifications sent out when enabled
/// Notifications for Sensor Notification characteristic value (handle 0x2A)
UINT8 sensor_data[];
