# Migrate USB Devices from Equipment Table

## Issue
6 USB devices were incorrectly stored in the `equipment` table instead of the proper `usbdevices` table.

## Status
- [x] `pin` field added to `usbdevices` table for encrypted devices
- [x] `pin` field added to USBDevice model
- [x] USB Device equipment type deactivated (equipmenttypeid=44)
- [ ] Migrate 6 USB devices to usbdevices table

## Affected Records
| Asset Number | Name | Serial Number |
|--------------|------|---------------|
| 82841957-5891 | Green Kingston 64GB | 82841957 |
| 48854302-5892 | Blue Kingston 64GB | 48854302 |

## Migration SQL

### Step 1: Insert into usbdevices
```sql
INSERT INTO usbdevices (
    serialnumber,
    label,
    assetnumber,
    usbdevicetypeid,
    storagelocation,
    notes,
    createddate,
    modifieddate,
    isactive
)
SELECT
    a.serialnumber,
    a.name,
    a.assetnumber,
    NULL,  -- Assign proper type later
    NULL,  -- Storage location TBD
    a.notes,
    a.createddate,
    a.modifieddate,
    a.isactive
FROM assets a
JOIN equipment e ON e.assetid = a.assetid
WHERE e.equipmenttypeid = 44;  -- USB Device type
```

### Step 2: Delete from equipment table
```sql
DELETE e FROM equipment e
JOIN assets a ON a.assetid = e.assetid
WHERE e.equipmenttypeid = 44;
```

### Step 3: Delete from assets table
```sql
DELETE a FROM assets a
JOIN equipment e ON e.assetid = a.assetid
WHERE e.equipmenttypeid = 44;

-- Note: Run step 2 first since it references assets
```

### Alternative: Manual Migration
Since there are only 6 devices, you may prefer to:
1. Manually create them in the USB Devices section
2. Delete the equipment/asset records

## USB Device Types to Create
```sql
-- Check if types exist, create if needed
INSERT IGNORE INTO usbdevicetypes (typename, description, icon) VALUES
('Flash Drive', 'USB flash drive / thumb drive', 'usb'),
('External HDD', 'External hard disk drive', 'harddisk'),
('External SSD', 'External solid state drive', 'harddisk'),
('Card Reader', 'SD/CF card reader', 'sdcard'),
('Optical Drive', 'External CD/DVD/Blu-ray drive', 'disc'),
('WiFi Adapter', 'USB wireless network adapter', 'wifi'),
('Other', 'Other USB device', 'usb');
```

## Notes
- USB Device equipment type has been deactivated (isactive=0)
- New USB devices should be created in the USB Devices section
- USB devices do NOT need map positions (no mapleft/maptop)
