Error on kobo driver

[Frogg]

Hi,

I'm "playing" with connexion on a Kobo with :

scanner = DeviceScanner()
scanner.scan()
device = KOBOTOUCH(None)
tmp = device.is_usb_connected(scanner.devices)
if tmp[0] != True:
    print("Kobo not find")
    exit()

print("Kobo find" + device.get_device_information())

I get the error :

  File "/usr/lib/calibre/calibre/devices/kobo/driver.py", line 1620, in get_device_information
    self.set_device_name()
    ~~~~~~~~~~~~~~~~~~~~^^
  File "/usr/lib/calibre/calibre/devices/kobo/driver.py", line 3912, in set_device_name
    if self.is2024Device():
       ~~~~~~~~~~~~~~~~~^^
  File "/usr/lib/calibre/calibre/devices/kobo/driver.py", line 3742, in is2024Device
    return self.detected_device.idProduct in self.LIBRA_COLOR_PRODUCT_ID
           ^^^^^^^^^^^^^^^^^^^^
AttributeError: 'KOBOTOUCH' object has no attribute 'detected_device'

Referring to :

    def is2024Device(self):
        return self.detected_device.idProduct in self.LIBRA_COLOR_PRODUCT_ID

But there is no self.detected_device = anywhere.
Do i miss something ?

You need to call open() first.

Hi,

thanks for your reply, but i don't get it (i use calibre-debug -e):

scanner = DeviceScanner()
scanner.scan()
device = KOBOTOUCH(None)
device.open(scanner.devices)

I get same problem

  File "/usr/lib/calibre/calibre/devices/usbms/device.py", line 504, in find_device_nodes
    detected_device = self.detected_device
                      ^^^^^^^^^^^^^^^^^^^^
AttributeError: 'KOBOTOUCH' object has no attribute 'detected_device'

Look at the main() function in devices/cli.py for the exact sequence of operations you need.

ok, it works, thx
its painfull, is there any full documentation or example for writing script ?

for example, i want to search book id in my library, it should be :

db.get_item_id(self, field, item_name, case_sensitive=False)

But there is no information about format of field or item_name, or what field cover. If i do :

db.get_item_id('authors', 'an_author')

i get the right id but if i do :

db.get_item_id('title', 'a_title')

using the title name from the .sql, it find nothing.
